摘　　要：针对工程中的柔性安装问题,以广义浮筏隔振系统为例,采用子结构导纳分析法,研究了复杂机械系统的动态传递特性,从功率流的观点对复杂机械系统的隔振效果评估问题进行了研究,验证了功率流传递率在评估系统隔振性能方面的有效性。Aimed at the installation of the machines on the flexible foundation, the dynamic transmitting characteristics of a complex floating raft system have been theoretically studied by the substructure mobility method. Further, the power flow transmissibility has been proposed and analyzed as a new comprehensive evaluation standard and its validity has been proved theoretically.
