摘　　要：采用Pro/Engineer和MSC.Patran相结合的方法创建浮筏隔振系统的有限元模型,通过MSC.Nastran对浮筏隔振系统做频域响应分析,并采用能量平均法对隔振效果进行评估,进一步研究浮筏隔振系统中主要结构参数变化对隔振性能的影响。Pro/Engineer and MSC. Patran were associated to establish the finite element model for the floating raft system. The frequency response analysis of the floating raft system was carried out in MSC. Nastran. The effect of vibration isolation was investigated by the power average method, as well as the influence of main structure parameters upon the isolation effect of the floating raft system.
