| 摘 要： | 建立了浮筏隔振系统的振子力学统计分析模型，使用导纳功率流的方法研究了隔振系统的振动响应和振动功率流特性，并通过数值方法分析了筏体和隔振器参数变化对传递到基础结构功率流的影响。分析结果表明：增大基础厚度、减小系统中耦合元件的耦合刚度和增大筏体质量可以有效控制系统的传递功率流。

| Abstract: | The oscillator mechanics statistical analysis modal of floating raft isolation system is founded in this paper.Then the vibration responses and power flow characteristics of the isolation system are studied utilizing the mobility power flow analysis method.Finally through numerical method,the effects of parameters of raft and isolator to the power flow that transmitted into the basic structure are analyzed.The results show that: it is effective to control the transmission power flow by increasing the thickness of the base,or decreasing the coupling rigidity,or increasing the mass of the raft. |
