摘要
本文提出了一种求解复杂结构系统动力响应的数值计算方法。该方法是自由界面部件模态综合技术的推广，在系统动力响应计算时只需用到各个子结构的模态参数和载荷特性，且不必求解整体系统的特征值问题。文末给出的算例表明该方法具有良好的精度和较高的计算效率。
A numerical method for solving the dynamic response of a complex structural sys tem is presented in the paper.This method is an extension of the free-interface method ofcomponent modal synthesis.The dynamic response of the system is computed on the base of the modal parameters and external loads of each substructure,without need to solve the eigen problem of the whole system.An namerical example shows the good acceracy of the results and high efficiency of the procedure.
