中文摘要：

基于频响函数的子结构综合方法，通过引入子结构连接特性的参数化模型，提出了一种将刚性连接特性和柔性连接特性统一处理的子结构建模与综合求解方法。将该方法用于试验子结构与理论子结构的混合建模与求解系统，实现了不同连接特性的多子结构的混合建模与综合求解。实例验证结果表明：该方法正确有效，且在子结构模拟试验数据存在一定随机误差的情况下也依然有效。

英文摘要：

On the basis of FRF substructuring method,parameterized connection property between substructures was taken into account ,which made connection parts independent of the connected sub- structure system. The general treatment of rigid connection property and flexible connection property was realized. At the same time, the hybrid modeling of test substructure and theoretical substructure was realized and the corresponding hybrid modeling solution system was developed. The numerical cal- culations show that this method can deal with flexible connections among substructures and is still ef- fective when stimulation test data of substructure is polluted by random errors.
