摘要
本文把结构动态特性计算的模态综合超单元法拓广至结构动响应的计算领域。由于结构模态对阻尼矩阵的非正交性带来的耦合阻尼项造成了响应计算的困难,本文采用了保持主对角项阻尼的响应运算,然后根据虚功原理对结果进行了耦合项阻尼的修正。
The model synrthesls super-element method for calculation of structure dynamic characteristics is extended to the calculation of structure dynamic response, which enlarges the using range of the method.Becanse of the difficulty of response calculation caused by the coupling damping term in the non-orthogonal dampiug of structural models, only the main diagonal damping terms are kept in the response calculation. The calculation resnlts are then modified by the coupling damping terms according to the virtual work principle.
