The abdomen-rubbing qigong exercise was first developed by Fang Kai, a Xin’an medical practitioner. It’s an essential part of Xin’an health preservation works. This health preservation method integrates massage with Daoyin and integrates meridian theory with Zangxiang theory. It’s safe, simple and has no side effects. Practice of this qigong exercise can protect the spleen and stomach, tonify qi and essence, harmonize Ying-Nutrients and Wei-Defense, unblock meridians and circulate qi. This paper aims to summarize and promote this exercise.

The digital design of mechanical products is usually first reference existing parts, drawings, and experience to make original design data and design requirements, according to the design of digital model is set up, after an analysis of the finite element model according to the analysis results contrast design goal to design or structure parameter changes, to the expected design purpose. Analysis of the product is an essential part of product design.

To improve the designers’ work efficiency, reduce the design strength, transportation pallet modeling was built through three-dimensional software Pro/E, and the model was secondary developed by using Pro/Toolkit, Pro/E secondary development tools. Designer design independent program interface for drive Pro/E parameters of three-dimensional modeling of the transportation pallet.

To improve the designers’work efficiency, reduce the design strength, ceramicgear modeling was built through three-dimensional softwarePro/E, and the model was secondary developed by using Pro/Toolkit, Pro/Esecondary development tools. Designer design independent program interface fordrive Pro/E parameters of three-dimensional modeling of the ceramic gear.

This paper analyzes the stamping process of a rigid gasket, designs a set of progressive die for gasket. Three-position of the die includes the punching, cutting, bending and blanking. And compared with single-process die and compound die, the gasket can obtain better surface quality, the die can prevent poor strength and partial load, and punching hole in the ear and separating bending process can improve the accuracy of stamping parts, it has some reference value for the progressive die of the stamping parts. Throughout the design process, the model of rigid gasket and 3D mold design are established in Pro/E4.0 and PDX, this can significantly shorten the design cycle; the process of open-mode is simulated in the Simulation module.

Globular indexing CAM mechanism is a good indexing mechanism. As the working curve of CAM contour surface is no extending curved surface, there is certain difficulty to design processing. It is new kinds of design method that reverse engineering apply in rapid modeling of curved CAM. In this way, designer can complete curve of CAM reverse modeling, and the rationality of the model is verified. At the same time, it also can reverse modeling and the subsequent development of other products to provide a reference.

Based on equations of gas diffusion equilibrium, a new design method, along with a CAD software package, was developed to improve the efficiency of fruit packaging design. Take guava fruit as a case study, the method we developed was used to calculate unknown pack parameters and simulate the dynamic change of in-pack gas concentrations. When the ratio of headspace and fruit volume was 2.5:1, it expended about 200 h before the equilibrium gas exchange was created. However, in the case of 0.3:1 ratio, it needed only 30 h to obtain the equilibrium state. Simulation results are useful for achieving high quality of package design, especially in the case of long transport distance or long-time storage.

In this paper, the problem of output tracking for a class of uncertain nonlinear systems is considered. First, neural networks are employed to cope with uncertain nonlinear functions, based on which state estimation is constructed. Then, an output feedback control system is designed by using dynamic surface control (DSC). To guarantee the L-infinity tracking performance, an initialization technique is presented. The main feature of the scheme is that explosion of complexity problem in backstepping control is avoided, and there is no need to update the unknown parameters including control gains as well as neural networks weights, the adaptive law with one update parameter is necessary only at the first design step. It is proved that all signals of the closed-loop system are semiglobally uniformly ultimately bounded and the L-infinity performance of system tracking error can be guaranteed. Simulation results demonstrate the effectiveness of the proposed scheme.
