| 摘 要： | 模态机械阻抗综合法是一种新的动态子结构振动分析方法，是传统机械阻抗综合法的推广。它克服了以往动态子结构分析中由于各子结构自由度数不同而带来的困难，并能求解弹性体一刚体系统振动问题。本文研究了模态机械阻抗综合法的求解步骤及其在复杂隔振系统振动分析中的应用，并以立体浮筏隔振系统为模型，进行了分析计算。

| Abstract: | Modal mechanical impedance synthesis analysis(MMISA) is a new subsystem vibration analysis method and a new approach based on traditional mechanical impedance synthesis analysis.It overcomes the difficulties produced by different degree-of-freedoms of each subsystem in substructure analysis.This method can be used to solve elastomer-and-rigid-body model.MHISA is introduced in this paper and the solid raft isolating vibration system is given as an example. |
