摘要
提出求解复杂结构系统动响应的一种计算方法。推导了子结构动响应的计算公式 ,利用静凝聚技术将每个子结构的内部坐标凝聚到界面坐标上 ,根据界面协调条件 ,求出界面的物理量 ,然后回代到各个子结构计算其内部的动响应。通过这样的方法进行综合分析 ,便于解复杂结构系统的动响应问题。
A method on dynamic response of complicated structural systems was put and the calculating formula was deduced. Using static condense technique, the inner coordinate of every substructure was condensed to interfacial coordinate so that the interfacial variables were calculated according to the condition of interfacial harmony. Then the inner response of every substructure can be calculated. It is easy to analyze dynamic response of complicated systems through such integrated method. In the end, a sample was given.
