提出了具有连接子结构的固定界面模态综合法。基于本方法编制了三个子结构的固定界面模态综合法程序。所结算例表明 ,该方法计算量小 ,精确度高 ,可用于复杂耦合系统的动态特性分析。
A fixed interface modal synthesis method with linker structure is proposed. Based on this method, three substructures of fixed interface modal synthesis program are compiled. The results show that this method has a low computational complexity and high accuracy and can be used to analyze the dynamic characteristics of complex coupled systems.
