摘　　要：本文对船舶浮筏装置的抗基础冲击特性进行了理论分析与试验研究。在建立隔振装置力学模型的基础上 ,推导了隔振机组的冲击加速度以及隔振器变形量的表达式 ,计算得到其与频率比及质量比的关系 ,讨论了浮筏参数的选取。在理论分析的基础上 ,通过船舶浮筏模型试验 ,研究了浮筏隔振装置对于船体基座冲击的响应 。The investigation on the anti-shock property of the floating raft installation was made both theoretically and experimentally.The Expressions of the shock acceleration of the equipment as well as the deformation of the isolator were deduced on the basis of the setting up of the mechanical model of the isolation system.Through the tests on the floating raft model,the response of the device was surveyed.Then the influences of the frequency ratio as well as the mass ratio on the anti-shock property was discussed.
