摘要:
本文借助状态空间,采用摄动有限元法对不定参数结构进行了动力分析.将复模态的二次特征值问题化为一次特征值问题,对不定参数在某一确定值邻域内的摄动,利用二阶摄动的有限元方法通过一次性计算得到了结构复特征值,状态特征向量的一、二阶摄动公式。
Abstract:
This article uses the state space to analyze the inferior parameter structure with the proclaimed element method. The secondary feature value problem of the reciprocating mode is used to the problem of one feature value problem. For the lata of the uncertain parameter in the neighborhood of a certain value, the finite element method using the second -order switch is obtained by a one or two -order switching formula of the status feature vector.
