一种模态力矩阵组装方法

Main Force Method,an Assembly Method of Modal Force Matrix

在对“模态力法”理论应用研究中，提出了模态力矩阵的一种组装方法——主作用力法．从对包含串联、并联、环型等常见子结构连接方式的实例分析结果可以看出，该方法简单，易于编程实现，且提高了计算速度，为模态力法的应用提供了可靠的手段．

Based on the applying research of the theory of modal force method, a kindof assembly method, the main force method is put forward, Several examples arepresented which nearly represent all the normal linkage means of substructures. Uponcomparing the assembly results from using main force method with those fromtheoretical means, it is turned out that the correctness of the applying, that is applyingmain force method to the assembly of modal force matrix, is verified, the difficulty ofprogramming with modal force method is reduced, and the reliable means of usingmodal force method is provided.
