两自由端多自由度振动系统计算程序设计

Program Design for Multiple Degree-of-Freedom Vibration System with Two Free Ends

对两自由端多自由度振动系统进行分析,阐述应用数值计算方法寻找系统主频率的方法。针对该种方法,基于VB语言,编写系统主频率和主振型的计算程序。针对具体系统给出计算结果。总结该程序的特点和局限性。

The multiple degree-of-freedom vibration system with two free ends was analyzed in this paper. The numerical method for finding the principal frequency of the system was proposed. The computer program for determination of the principal frequency and the corresponding vibration mode was written in VB code. Numerical results were given for some examples of the system. Advantages and limitations of the program were also summarized.
