一种瞬态动力分析的子结构方法

A Substructuring Method for Transient Dynamic Analysis

本文提出了一种计算结构瞬态动力响应的子结构方法。这种方法能充分考虑结构不同部位力学特性的差异,允许在不同部位采用不同的逐步积分方法,从而提高计算效率。采用这种方法还可缓和结构规模和计算机容量之间的矛盾。

A substructuring method for transient dynamic analysis of structures is pre- sented in this paper.Different step-by-step integration method can be applied to different parts of a structure according to their mechanical characteristics,thus the method is eomputationally efficient.Besides,large scale problems can be solved with small computers by this method.
