摘要
文中对阻尼振幼系统实模态分析的条件问题作了进一步的讨论,给出了可解耦阻尼矩阵的空间结构,同时说明了实模态矩阵的确定问题。
This paper futher discusses the condition of the classical modal analysis about damped vibration systems.It shows the space construction of orthogonalized damping matrices and then explains the determination of the classical modal matrix.
