应用加权残值法求解结构动力学问题

Applying weighted residual method solving structural dynamics problems

简单介绍了加权残值法的特点、基本原理及国内研究现状,并结合具体算例阐述了采用配点法计算的优势,指出在适当情况下,是可以采用加权残值法取代有限元进行工程力学分析的。

With a brief description on the characteristics,basic principles and domestic research status of weighted residual method,combining with specific examples,it expounds the advantages of point collocation calculation method.And then,it points out that engineering mechanics can be analyzed with weighted residual method in stead of finite element under appropriate situation.
