| 摘 要： | 利用广义模态理论,寻求重频亏损系统状态矩阵的广义状态向量,然后引入其伴随向量,形成规范正交化条件,从而解耦振动微分方程,将其化为一组一阶可分离和线性的微分方程,获得自由响应的解析解。

| Abstract: | On the basis of generalized mode theory,the generalized state vector of state matrix in repetition frequency defective system is found,and then the adjoint vector is introduced to form normal orthogonalized condition,so as to decouple the vibration differential equation,which turns it to a set of first-order separable linear differential equations and gets the analytical solution to free response. |
