Lead-cone waveform generator (LCWG) is one of the crucial components in shock tests to generate final-peak saw-tooth shock pulses which are widely used to evaluate the safety and reliability of structure/equipment under shock environment in laboratory. With aim to generate a desired final-peak saw-tooth waveform and develop its dynamic model, it is necessary to investigate the working mechanism of LCWG in impact conditions. In this work, a series of customized shock tests based on LCWGs were performed by using a drop test machine (DTM). Meanwhile, the regulation effects of several core characters, including the aspect ratio (h/2R) of LCWG, the impact velocity, and the impact mass, on the generated final-peak saw-tooth waveforms are studied systematically. Experimental results showed that the overall geometric shapes of LCWGs varied from cone to truncated cone during impact processes, accompanying with local non-uniform deformation near the contact position. The correlation analysis indicated that peak acceleration of the generated final-peak saw-tooth waveform increased linearly with the increasing impact velocity, the impact mass, but decreased exponentially with elevated aspect ratio of lead-cone; the pulse duration of the generated final-peak saw-tooth waveform exhibited nonlinear increase trend with the increase of aspect ratio, but was not sensitive to the changes of impact velocity and impact mass. Subsequently, a nonlinear dynamic model of LCWG to predict the final-peak saw-tooth waveform was established by incorporating the geometric deformation model of the lead-cone during impact process and the mechanical constitutive model of the lead. The proposed model considered main parameters of the LCWG in shock tests, including the impact mass, the impact velocity, the geometric dimensioning of the LCWG, and the mechanical properties of lead. The predicted waveforms based on the established model agreed well with the experimental shock pulses, which provided a basis design for shock test.

The article presents the research results on the influence of variable shock conditions, such as temperature and water, thus reflecting shock atmospheric conditions during freezing and thawing, on the properties of samples produced using 3D printing technology from commonly used materials such as ABS, HIPS, PLA, and ASA. Understanding how different environmental conditions affect the quality, reliability, and durability of 3D prints can help to optimize the printing process and provide valuable information about their application possibilities. Tests related to the strength of the materials, such as static tensile testing, Charpy impact testing, and evaluation of structures, were carried out using a scanning electron microscope (SEM). Changes in chemical properties were measured by performing tests such as FTIR and TGA. Variations in chemical properties were measured by performing tests such as FTIR and TGA. One shock cycle lasting 7 days was sufficient to alter the properties of 3D prints, with the extent of changes depending on the material, as summarized in the test results. [ABSTRACT FROM AUTHOR]

Elastomer materials are widely used as shock absorbers in a variety of practical applications including the automotive, aerospace, marine industries and structures. The straightforward Hooke's law is insufficient to adequately describe the behavior of elastomeric materials due to their nonlinear elastic and viscous properties. This study proposes a hyper-viscoelastic model to describe the mechanical behavior of Hydrogenated Nitrile Butadiene Rubber (HNBR) 62 Duro shore A and Polychloroprene Rubber (PCR) 55 Duro shore A. Six distinct hyperelastic models—Yeoh, Rivlin, Arruda-Boyce, Mooney-Rivlin, Neo-Hookean, and Ogden— are compared herein to explain the nonlinear elastic behavior of elastomers. While the time-dependent characteristics of the considered materials have been described using the four parameters Generalised Maxwell (GM) model. The material parameters of models are determined using the least square fit (LSF) optimization algorithm from the uniaxial, planar, and stress relaxation test data. The stability and suitability of each hyperelastic model is assessed using the Drucker stability. The accuracy of each model is represented by Root Mean Square Error (RMSE) of curve fitting between theoretical and experimental data. On this basis, the Ogden order three (N = 3) model and the four-parameter GM models are selected which well agreed with the experimental test data and they are integrated to generate the hyper-viscoelastic constitutive model. In addition, the hyper-viscoelastic model is used to simulate the HNBR and PCR dampers under shock load. The numerically generated response is finally compared with the experimental test result of natural rubber (NR) 60 IRH from the existing literature to confirm accuracy of the proposed model.

Marman clamp band separation mechanism is often used to separate a satellite from a launch vehicle. During the separation, the Marman clamp band releases its clamped force and to expose the satellite to a harsh environment of high-magnitude acceleration with high-frequency in a short period of time, which is named by shock environment in spacecraft developments. Estimation of the shock environment is necessary to specify the equipment design condition which is used to design the equipment’s capability to endure shock environment. Empirical methods based on past development shock test data, due to their convenience and simplicity, are often used to estimate the shock environment. However, the accuracy of empirical methods derived by the past shock test data may be affected by the different structural characteristic of the satellite which was not involved in the methods. There are two typical empirical methods, named by conventional empirical methods in this paper, which are widely used in space development. However, there are no discussions and comments regarding the uncertainty of the estimation and this unknown uncertainty will lead to over conservation safety margin assigned when applying the estimated results to specify the design condition of equipment. To answer the questions as mentioned about the conventional empirical methods, first, we investigate the applicability of conventional empirical methods by two different structural characteristics of JAXA satellites, and second, we propose the improved empirical methods for the two different types of structural characteristics based on shock test data during Marman clamp band separation test. Furthermore, a margin used to envelope the uncertainty of individual test data is statistically derived and its applicability is demonstrated from the test data.

Various types of mechanical energy-absorbing devices are known that operate by plastic deformation. The corrugated ring mount that is used in this study relates to a device that absorbs energy by plastic deformation. This energy-absorbing device has reduced volumetric proportions, simple in design, and therefore has small overall dimensions and can be mass-produced at low cost. This study aims to determine the shock absorption capability and efficiency of this mount against impact loading. For this, Finite Element Method Analysis (FEA) and experimentation are done. The FEA is done using the Explicit Dynamics (AutoDyn) module of ANSYS Workbench and for experimentation Drop Test Machine (DTM) is used. In this study impact load from low g up to 85 g is applied and a very close agreement is found between FEA and experimental results. There is just a 5–10% deviation between the findings. The results show that this mount is plastically deformed to absorb the impact energy with a maximum efficiency of 70%. It concludes that it is a reliable and safer shock energy device.

The primary concern of the current study is estimating the repetitive shock induced damages leading to cumulative fatigue on corrugated cardboard boxes experimentally and numerically. Repetitive shock tests were performed on boxes using a vibration table to construct a Damage Boundary Curve (DBC). To computationally determine this curve, a finite element approach is proposed using an elastoplastic homogenization model for corrugated cardboard. The proposed model was implemented in the finite element software ABAQUS. Thanks to adopted model simplifications, a box can be easily and reliably modelled as a homogenized structure. A calibration method is used to compute a set of effective parameters in homogenized model in order to keep its behavior qualitatively and quantitatively close to the response of a full structural model. For verification, the identified model is used to simulate the box compression test. To replicate the experimental tests, simulations of successive repetitive shock pulses are carried with the proposed model for oligocyclique and limited endurance fatigue. To reduce computational costs, we propose a simple method for unlimited endurance fatigue by extrapolating a trend line after some training cycles. The proposed method shows good agreement with experimental results.

In this paper, we propose a bistable shock structure based on the thermal actuation principle, which overcomes the response time limitation of heating and cooling in typical thermal actuators and enables a rapid release of energy. Thus, force with a steep rising edge can be applied on a target. Using a bistable shock structure to generate on-chip shock loads, we propose an automated and resettable method for shock testing of microstructures. We characterize the microscale shock process by high-speed camera and finite element simulation (FEM). The method can simulate the dynamic response of key structures in MEMS devices under mechanical shock conditions, and therefore, can be used to evaluate shock fracture strength of microstructures.

A nonlinear dynamic model for describing shock response of half-sine programmer in shock test is constructed, in which many important factors in half-sine programmer such as size, hard nonlinearity, damping and initial impact velocity are considered, based on the damped Duffing equation, and the empirical static stiffness and shock stiffness calculation formulas of cylindrical rubber isolator. The shock pulse of half-sine programmer is measured and calculated by using shock test machine and Runge-Kutta method. Taking the minimum determination coefficient between the calculated and the measured shock pulse as the optimization objective, the parameters in the present model are determined by using quantum genetic algorithm (QGA), and meanwhile the extreme capacity in the present model for describing the dynamic behavior of half-sine programmer under shock excitations can also be verified. Experiments were implemented with drop shock test machine. The experimental results show that the present model is precise and efficient, and the prediction errors of pulse peaks and pulse widths were all below 5%, the waveform fitting errors between the calculated and the measured pulses are all less than 15%. The present results are helpful for designing the half-sine programmer.

Large shock responses are generated at the deployment of solar paddles and antennas of a spacecraft because the strain energy of retained parts are released almost instantaneously. Therefore, the shock resistance of spacecraft instruments must be verified before launch. Specially designed separation mechanisms or explosive devices have been used for spacecraft separation, but shock testing using these devices is costly, so alternative methods such as mechanical impact testing are used. Adjusting the shock response spectrum (SRS) in these tests to desired values is a difficult task that requires considerable expertise. In this paper, we present a method for tuning an SRS. This method involves inserting a structure between the base plate of shock tester and the test specimen in order to modify the vibration propagation characteristics. Due to its easy implementation, this method can also be applied to other mechanical shock testers in use. In addition, a method for predicting the SRS using the transfer function synthesis method is also proposed to facilitate the adjustment of the test level.

Effects of the rotational component on a prediction result of the shock response spectrum given by a transfer function synthesis method are discussed. Shock environment on two structure models, which are a plate model connected by two flat plates and a shock tester model installing a test specimen, is analyzed. The transfer functions of the substructures in these models are initially computed and are synthesized to predict the shock response spectrum in the coupled structure. In the synthesis analysis without the rotational component, the prediction accuracy of the shock response spectrum in the plate model significantly decreases, whereas that in the shock tester model is unaffected. This is attributed to the fact that the shock tester model has high flexible rigidity originated from its structural configuration. This result indicates that the shock response spectrum on the shock tester model can be predicted with sufficient accuracy by only synthesizing the transfer functions with the translation component.

Gas bearings enable microturbomachinery (MTM) with a large power to weight ratio, low part count, and nearly frictionless motion, thus resulting in systems operating over extended maintenance intervals and with improved fuel efficiency. Envisioned oil-free vehicle transportation systems implementing gas bearings range from small size gas turbines, to unmanned aerial vehicles, to turbochargers (TC), and more to come. In these vehicles, base or support transient displacements transmit forces exciting the rotor-bearing system; hence, the need to characterize system integrity under stringent operating conditions. This paper reports experiments demonstrating the ability of a hybrid gas bearing-rotor system to withstand maneuver actions that suddenly remove the ground support. The test rig consists of a rigid motor-rotor, supported on tilting pad hybrid gas bearings supplied with pressurized air. The rotor is housed in a thick steel casing that is attached to a rigid base plate. The whole test rig hangs from a crane; two steel cables connect to one side of the base and a nylon webbing attaches to the other side of the base. The other end of the webbing ties to a release mechanism, which when released, frees one side of the rig base. Suddenly, the whole test rig rotates and displaces downward while the tensions in the taut cables rapidly increase and pull the test rig as it swings back and forth. The crane support enables two release maneuvers: one turns the rig ~90 deg and the other flips it 180 deg, both events occurring while the rotor spins at 70 krpm (surface speed 105?m/s). The measured rotor displacements relative to the casing demonstrate a momentary increase in motion amplitude, up to ~1.15?mm since the bearings also displace, along with a maximum casing deceleration of ~7?g when the cables stop the rig fall. The measurements show the rotor response is free of subsynchronous whirl frequencies that could evidence a rotor dynamic instability. Very low frequency motions denote the swing frequency of the hanging rig and jerk motions from the crane lifting and bouncing when the rig is at its lowest vertical position. In one instance, power to the motor unexpectedly interrupted and the rotor underwent an unplanned shaft speed coastdown. In spite of the large displacements recorded, the rotor survived both events; it continues to operate to this day. The experiments demonstrate that the hybrid gas bearing system could withstand large amplitude rotor excursions. The measurements provide a novel method for testing gas bearings, as the induced excitations are multidirectional, while the test rig encounters a short period of free falling, followed by a quick deceleration with large forces. A simple kinetics model of the test rig drop produces peak decelerations similar in magnitude to those measured. [ABSTRACT FROM AUTHOR]

Satellites are exposed to various shock environments during launch. Large shock responses can be generated on rocket separation or deployment of solar arrays and antennas when the strain energy of retained parts is released. Therefore, a test to verify the shock resistance of spacecraft components is necessary. Specially designed separation mechanisms or explosive devices are used to facilitate separation but such methods are expensive to test. To reduce this cost, alternative methods (such as the falling weight shock method) are used but the shock excitation source and structural propagation paths of the test apparatus are different from the operational configurations. This poses problems in making adjustments to match the specified Shock Response Spectrum (SRS) and often causes over- and under-testing, decreasing confidence in the test. This paper reports the results of our study to improve the accuracy of the SRSs of satellite components in shock testing. In the mechanical impact method implemented by the drop weight shock test, the SRS is usually adjusted by changing the material at the impact point, but this method is often inadequate. Rather than changing the hardness of the impact point we modified the SRS adjustment by altering the structure in the path of shock propagation. [ABSTRACT FROM AUTHOR]

A deep learning based approach is proposed to accurately recover shock signals measured from a damaged high-g accelerometer without modifying the hardware. We first conducted shock tests and collected a large dataset of shock signals with different levels of acceleration by using an efficient experimental apparatus. The training data is composed of a pair of signals simultaneously obtained from a faulty accelerometer and a high-end accelerometer (served as the ground truth). A customized autoencoder neural network is designed and trained on this dataset, aiming to map the faulty signals to their reference counterparts. Experimental results show that, with the help of deep learning, shock signals can be accurately recovered from the faulty measurements. Compared with conventional approaches that require diagnosing and replacing faulty parts, the proposed data-driven method demonstrates a highly promising solution that allows recovering corrupted signals without introducing extra work to upgrade the hardware at almost zero cost. The dataset and code of this work are made publicly available on GitHub at https://github.com/hope-yao/Sensor_Calibration. [ABSTRACT FROM AUTHOR]

An optimum cushioning package, which is neither excessive nor inadequate, must be designed to ensure cushioning performance that maintains an acceptable failure rate during transportation while also minimizing packaging costs. For this purpose, statistics pertaining to transport hazards and product shock strength must be engaged. The proposed study presents a test method to enhance the statistical accuracy of mechanical shock fragility of products. Sample statistics are invariably unknown; hence, optimum test‐setting values cannot be determined at the beginning. The proposed test method has been devised for determining optimum test‐setting values of the (n + 1)th sample using statistics of n samples being tested. An improvement in the estimation accuracy of the variation coefficient for the critical‐velocity‐change test was confirmed via simulations performed using the proposed method. Optimization of the test‐setting value has also been experimentally confirmed. A comparison of histograms and statistics obtained using experimental results has demonstrated that the proposed method can better estimate distribution shapes compared with the simple method. An example of the application of experimental results to stress‐strength models has also been described. The observed result has a considerable influence on the design of cushioning packages, thereby demonstrating effectiveness of the proposed method. A test method that enhances the accuracy of estimating product statistics with regard to mechanical shock fragility has been proposed. Improvement in estimation accuracy of the variation coefficient concerning the critical‐velocity‐change test has been confirmed via simulations. The observed result has a considerable influence on the design of cushioning packages. [ABSTRACT FROM AUTHOR]

The sliding bearing is an important component of propulsion shaft in ship; its stability is the basic promise of maneuverability. A large-sized sliding bearing on board as the subject was investigated. The experimental shafting system for simulating installation state and wording state on board was specially developed. The shock tests were carried through on floating shock platform subjected to underwater explosions. The test results showed that the rubs appeared between the bushing and shaft during intense vertical impact loading,as a result the operate moment of torque was instantly increased about 200%,which presented more requirements for shafting power. Due to the smaller intensity of transverse shock loading,the vibration amplitude was under the scope of bearing gap. Through these shock tests of sliding bearing,the dynamic model of oil film in present application does not appropriate for shock response analysis. This research presents reference for modifying shock dynamic model and increasing the simulation accuracy of shafting system.

The application of gyroscopes in harsh environments has always been a hot topic. As a high-quality material for manufacturing gyroscopes, quartz crystals need to be designed and optimized to meet the normal operation of gyroscopes in harsh environments. The Micro Electronics Mechanical System(MEMS) quartz tuning forks resonant gyroscope is one of the quartz gyroscopes. The elastic structure (V-shaped beam) between the anchor support point and tuning forks plays a vital role in the MEMS quartz tuning forks resonant gyroscope. This structure determines the natural frequency of the gyroscope, and more importantly, determines the shock resistance of the gyroscope structure. In this article, the MEMS quartz tuning forks gyroscope with different V-shaped beam thicknesses are simulated and analyzed by finite element analysis simulation software. After the modal analysis and shock simulation (the half-cycle sine shock pulse with amplitude of 1500 g (g is the acceleration of gravity) and duration of 2 ms in the six shock directions), the results show that when the beam thickness is 80 μm, the maximum stress is 94.721 MPa, which is less than the failure stress of quartz crystal. The gyroscope’s shock resistance is verified through shock testing.

Highlights • FBG geophone with acceleration limit is designed for weak signal detection. • Environmental tests verify its reliability as oil & gas industry product. • FBG geophone shows higher SNR compared to conventional moving-coil geophone. • Seismic cross-section profiles were obtained by FBG geophone array in field tests. Abstract A fiber Bragg grating (FBG) based geophone is designed for low-frequency signal detection. It has high acceleration response of about 60 dB re pm/g in a low frequency range of 5–60 Hz. However, the basic sensing principle of stretching FBG requires much more delicate and reliable packaging design and technology. Especially the high sensitivity at low frequency challenges the reliability in packaging, transportation and installation of sensor. To guarantee normal operation in field test and practical application, an acceleration amplitude restriction is added in the mechanical design of the FBG geophone. Then a series of environmental and reliability tests have been proceeded with online or offline monitoring of its working performance, including high & low temperature test, vibration test, shock test and tensile test, strictly according to National standard and Oil & Gas Industry Standard. The experimental results indicate that our FBG geophone meet the criterion of oil and gas industry product and is capable of field application. Finally, in the filed blasting tests, the seismic cross-section profile was obtained by use of FBG geophone array which shows the advantage in low frequency signal acquisition compared to conventional move-coil geophone.

This paper proposed a highly accurate nonlinear dynamic model and parameters identification method to predict the shock pulses generated by rubber waveform generator (RWG) used in shock test. The establishment of the model is based on the primary results of the Duffing equation, Pan-Yang model and empirical stiffness formulae of cylindrical rubber isolator. We proposed a series of measures to eliminate the interferences in the drop shock test experiment, which are also of benefit to design, regulate and calibrate drop shock testers. The overall nonlinear system is solved in time domain with Runge–Kutta. And the parameters of the nonlinear dynamic model are identified by minimizing the holistic shape difference between experimental and predicted shock pulses with multiple population genetic algorithm. Meanwhile, the capacity of this model in characterizing the dynamic behavior of RWG under shock excitations is also investigated. Compared with previous work, our model considers nonlinear viscoelasticity of RWG, the geometric factor of RWG and the effect of initial shock velocity, which makes our model more accurate and general. Experimental results shown great agreements with the predictions and that the proposed method can determine the parameters conveniently and synergistically. [ABSTRACT FROM AUTHOR]

This article reports the latest development of a wireless sensing system, named Martlet, on high-g shock acceleration measurement. The Martlet sensing node design is based on a Texas Instruments Piccolo microcontroller, with clock frequency programmable up to 90 MHz. The high clock frequency of the microcontroller enables Martlet to support high-frequency data acquisition and high-speed onboard computation. In addition, the extensible design of the Martlet node conveniently allows incorporation of multiple sensor boards. In this study, a high-g accelerometer interface board is developed to allow Martlet to work with the selected microelectromechanical system (MEMS) high-g accelerometers. Besides low-pass and highpass filters, amplification gains are also implemented on the high-g accelerometer interface board. Laboratory impact experiments are conducted to validate the performance of the Martlet wireless sensing system with the high-g accelerometer board. The results of this study show that the performance of the wireless sensing system is comparable to the cabled system. [ABSTRACT FROM AUTHOR]

In this study, an anaerobic baffled reactor (ABR) with seven chambers was applied to treat medium-strength synthetic industrial wastewater (MSIW). The performance of startup and shock test on treating MSIW was investigated. During the acclimation process, the chemical oxygen demand (COD) of MSIW gradually increased from 0 to 2,000 mg L−1, and the COD removal finally reached 90%. At shock test, the feeding COD concentration increased by one-fifth and the reactor adapted very well with a COD removal of 82%. In a stable state,Comamonas, Smithella, SyntrophomonasandPseudomonaswere the main populations of bacteria, while the predominant methanogen wasMethanobacterium. The results of chemical and microbiological analysis indicated the significant advantages of ABR, including buffering shocks, separating stages with matching microorganisms and promoting syntrophism. Meanwhile, the strategies for acclimation and operation were of great importance. Further work can test reactor performance in the treatment of actual industrial wastewater. [ABSTRACT FROM AUTHOR]
