| 摘 要： | 通过对聚氨酯泡沫塑料的动力学特性进行试验和理论研究，发现聚氨酯泡沫塑料在不同频率与不同振幅作用下其隔振力与位移呈现出典型的迟滞非线性，而且系统的动刚度是频率的非线性函数，与振幅基本无关；阻尼是振幅，速度，频率以及位移的非线性函数，在此基础上本文提出了描述隔振支承系统的动力学方程，并进行了参数辩识。计算与试验比较，吻合较好。

| Abstract: | By the test and theory research of the dynamics property of foam,discovers that the relation of the isolated force and the displacement show typical hysteresis nonlinear,that the stiffness of system is the nonlinear function of frequency and has nothing to do with the swing,that the damping is the nonlinear function of the swing?velocity?frequency and the displacement. |
