摘 要: 利用模态综合法技术结合并行机特点提出一个求解复杂系统动响应的模态综合法。该方法可不必求整体模态,而利用子结构连接条件直接确定各子结构的动响应,算例表明该方法是有效的。 A parallel free interface modal synthesis algorithm,combined with the charaters of parallel computer and the technique of free interface modal synthesis,for time history analysis of complex structures is presented and evaluated.It does not need to get whole eigenvalues and eigenvectors,and can decrease the scale of substructural model.The time history analysis of each substructures can be made directly by using connected conditions between substructures.Numerical examples showed that the algorithm had good accuracy and high efficiency.
