针对现有的大型机械动力学设计的复模态矩阵摄动法不能简单地唯一确定特征向量的所有摄动系数这一缺陷，作者在文［１］中通过引进一个简单的范化条件，导出了孤立复特征值情况的复模态矩阵摄动公式。但该法对系统存在重特征值时失效。为此，本文进一步研究了重特征值的复模态矩阵摄动法，详细导出了相应的摄动公式。 The complex modal matrix perturbation method for the existing large mechanical dynamics design can not simply uniquely determine all the perturbation coefficients of the eigenvector. The author introduced a simple normalization condition in [1] The Complex Modal Matrix Perturbation Formula for Solving Ordered Complex Eigenvalues. However, this law lacks validity when there is a heavy eigenvalue in the system. To this end, this paper further studies the complex eigenvalue complex mode matrix perturbation method, and derives the perturbation formula in detail.
