Abstract

A vibration absorption meta-structure with strong nonlinear stiffness is proposed by combining concepts of the vibration absorber and meta-structure. An experimental setup comprising the meta-structure and a primary oscillator is designed. The results of ultraslow linear sweep and fixed-frequency harmonic excitation tests show that the meta-structure can suppress the vibrations of the primary oscillator with different stiffnesses. Moreover, the meta-structure changes the resonance frequency band of the test system to an acceptable range when softer springs are used in the primary oscillator. The primary oscillator and meta-structure have almost the same phase when the resonance occurs, resulting in an acceptable change. Another meta-structure mode is activated as its frequency increases, inducing an additional resonance band when a harder spring is attached. Furthermore, permanent magnets are installed in the meta-structure to form a bistable characteristic, and the influences of the number of magnets on the vibration reduction are analyzed. When the meta-structure has twelve magnets, the high-frequency resonance peak is eliminated because the magnets can suppress the second mode of the meta-structure. The wavelet analysis is conducted to detect the frequency components. The meta-structure results in energy spread from the excitation frequency to the other frequencies. [ABSTRACT FROM AUTHOR]

Abstract

Laboratory experiments on circuits that exhibit transient effects are usually performed with a periodic input signal (like a square wave). Three experiments on a resistor capacitor (RC) filter using transient analysis and the solution of a first-order differential equation are described. The results according to a Fourier analysis are then reinterpreted. The similarities and differences in the results from the two theories provide a better understanding of both. Also, using Fourier analysis introduces the basic strengths and weaknesses of discrete signal processing. Further additions to this laboratory are discussed and include 1) the addition of more first-order linear circuits; 2) the addition of second-order (and higher-order) linear circuits; 3) the processing of all data in the frequency domain; and 4) the study of nonlinear circuits. Index Terms--Discrete signal processing, Fourier series, periodic function, phasor, RC filter, transient.
