摘要
本文提出由低到高逐阶地用渐近消除余量的手段,计算多自由度系统的固有频率的简便算法.可求出全部固有频率,且可达所需之任意精度.运算时只需计算器.
This paper presents a new gradual approximate method based on weighted residual method to solve the natural frequencies,for multidegree-of-freedom system.The method is quite simple and the examples show that it possesses the advantages of hi-gher accuracy, less computation and with calculator only needed.
