摘要

以FS-2-80橡胶隔振器为研究对象，进行了动态特性的试验研究和本构研究。试验研究得到了隔振器力-位移迟滞曲线。采用M-RT本构模型对隔振器进行了本构行为研究，考虑了频率、动态位移幅值的影响，通过与实验结果的比较分析，表明该模型能较好地描述该隔振器的动态本构行为。基于M-RT模型，分析得到了动刚度、动态阻尼与幅值、频率之间的关系，说明隔振器在低幅值下动态特性具有非线性。

Abstract

Experimental and constitutive study on dynamic characteristics of FS-2-80 rubber isolator were conducted. M-RT model to consider the influence of frequency and dynamic displacement amplitude was used to describe dynamic constitutive behavior of the isolator. The comparison between the experimental and predicted results showed that the model in the paper could preferably well describe the dynamic constitutive behavior. Based on the M-RT model, the relationship between dynamic stiffness, dynamic damping and amplitude, frequency was discovered. The nonlinear characteristics of FS-2-80 rubber isolator under small amplitude were also studied.
