| 摘 要： | 模态机械阻抗综合法(MMISA)是近年发展起来的一种新的子结构振动分析方法.它能求解含弹性部件系统的振动问题,同时克服了以往在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,是传统机械阻抗综合法的推广.本文研究分析复杂隔振系统力学建模的模态机械阻抗综合法和其在振动分析中应用,通过浮筏隔振系统算例,讨论了弹性体模型和刚体模型的计算结果.

| Abstract: | Mode Mechanical Impedance Synthesis Analysis (MMISA) is a new developing subsystem vibration analysis method in recent years.This method can be used to solve the vibration of flexible systems,it overcome the difficulties produced by different degree-of-freedoms of each subsystem in substructure analysis as well.It is a new approach based on traditional mechanical impedance synthesis analysis.A flexible raft isolation vibration system is given as an example,and the numerical modeling approach is discussed by MMISA in detail. |
