摘　　要：文章结合核电堆水下电火花加工时所用到的加工水泵需要隔振的要求,运用了3种方法来建立加工水泵浮筏隔振系统的动力学影响因素模型,3种方法为:结构导纳法、阻抗法、广义四断参数法,对浮筏隔振系统进行了数值仿真分析,在基于浮筏重量因素、刚度因素、阻尼因素的基础上,找出各因素对浮筏振动功率的影响规律,并提供浮筏结构设计时的重要参考准则。In this paper,three methods are used to establish the dynamic influence factor model of the floating raft vibration isolation system of the processing water pump according to the vibration isolation requirements of the processing water pump used in the underwater EDM of the nuclear power reactor.The three methods are the structural admittance method,the impedance method and the generalized four break parameter method.Numerical simulation of floating raft vibration isolation system is analyzed.Based on the weight factor,stiffness factor and damping factor of floating raft,the influence law of each factor on the vibration power of floating raft is found,and the important reference criterion of floating raft structure design is provided.
