摘　　要：针对工程实际中弹性浮筏复杂隔振系统 ,建立了柔性基础上机组多扰源弹性浮筏耦合隔振系统动力学普遍模型 ,给出了系统动态特性结构化分析方法。根据工程中两机组浮筏隔振系统功率流数值计算结果 。In this paper,a generalized theoretical model of floating raft vibration isolation system is presented,and the corresponding structral analysis method is developed to predict the power flow characteristics.Being based on the above,numerical calculation of the transmitted power flow for practical floating raft coupled system is performed to explore the effects of mount frequency and isolator damping on the flexibility of supporting structure and transmitted power flow within the ovweall system.
