多自由度系统扭转振动的微机分析与计算

The Computer Analysis and Calculations of Tossional Vibration of Multi Degree—of—freedon Systems

机械中多自由度系统的扭转振动是不可忽视的动力现象的重要问题之一,对多自由度扭转振动固有频率和固有振型的分析和计算,有许多种近似方法,但计算都比较复杂。本文用扩展的CBASIC语言,编写扭转系统固有频率和固有振型的计算程序,应用计算机对实际机械中多自由度系统扭转振动的刚度进行校核。

It is one of main questions of dy namics phenomenon not to be ignore tossinal vibrations of multi degree - of - freedom systems in the mechanism. There are many approximate calculation methods, but they are all more complicated in the analysis and calculation of intrinsic frequency and vibration model. The article introduce calculation program of intrinsic frequency and vibration model. The program is be writing out with advanced CBASIC language. It also introduce rigidity check of tossional vibration of multi degree — of —freedom in practical mechanism.
