摘要
通过改变坐标标度,直接写出了多自由度振动系统的频率特征矩阵,介绍了用频率特征矩阵的伴随矩阵的任一列求简正坐标的方法,讨论了系统的简正振动模式,并举例说明.
The characteristic frequency matrix of the multidimension free vibration can be directly obtained by changing the coordinate scales. The normal coordinates and normal vibration modals of multidimension free vibration can be obtained by using arbitrary row of adjoint matrix of the frequency eigen matrix, and two examples are given in this paper.
