摘要
定义和解释了复模态方法中各参数的意义,推演复模态问题转化为实模态问题的条件。并推导由实模态构造复模态的一般公式,最后通过算例验证本文的一些结论。
In this paper, the definitions of parameters in complex mode method are given and explained. The transformation from complex mode to normal mode is deduced. Based on this condition, the general formulas for making up normal mode shape into complex mode shapes are derived. The validity of the conclusion is verified by numerical examples.
