摘要

从数学物理方程角度出发，研究层状周期结构的动力衰减域特性。分析衰减域三个控制因素及影响因素。对有限层状周期结构，进行动力谐响应及瞬态响应分析；振动台隔震性能试验表明，层状周期结构对外部激励具有隔离或减弱作用。该研究为层状周期结构用于工程结构隔震、减振奠定了基础。

Abstract

The vibration attenuation zones of a laminated periodic structure have been studied. Effects of material and geometry properties on the three important parameters of the first attenuation zone were studied. The harmonic and transient responses as well as experimental test of a finite laminated periodic structure were conducted to highlight the vibration attenuation when the frequency falls into the band gaps. The present investigation provides a sound background for the application of laminated periodic structures in isolation or vibration attenuation for engineering structures.
