结构动态灵敏度分析的摄动有限元方法及程序设计

THE PERTURBATION FINITE ELEMENT METHODIN THE DYNAMIC CHARACTERISTICS SENSITIVITY ANALYSIS AND THE PROGRAM DESIGN

本文利用摄动有限元方法研究了局部结构多个参数单独或同时发生变化时的动特性灵敏度分析,并编制了计算程序,为结构的动力修改和优化设计提供了一种有效的计算方法。

This paper studies the dynamic characteristics semsitivity with the perturbation finite el-ement method when modifying one or many parameters of the partial structure, draw up the computing program, provides a effective calculating method for the structural dynamic modi-fication and optimal design.
