摘要
以一个自由边界条件的铝合金梁为例,采用了数值模态分析和试验模态分析两大类方法,对其振动模态进行了研究,最后对结果进行了对比验证和总结。本文重点是试验模态分析,阐述了试验模态常用的几种方法,对各种方法的优缺点做了对比总结。
Based on an example of a free-free beam,this article,using numerical and experimental model analysis methods,studies the vibra tion and model shape of this beam,and discuss the comparison of it.The main point of this article is the experimental mechanics,in which it explains the normal approaches of it and tells the differences between them.
