建立了浮筏隔振系统的振子力学统计分析模型，研究了稳态随机力激励下“浮筏”隔振系统的振动响应和振动功率流统计特性，并通过数值方法分析了筏架和隔振器参数改变对传递到基础结构功率流的影响。分析结果与采用导纳分析方法及传统隔振理论分析结果的一致性，表明本文的分析是正确的。
The statistic analysis model of the vibration of the floating raft vibration isolation system is established. The vibration response and the statistical characteristics of the vibration power flow of the “floating raft” vibration isolation system under steady state random excitation are studied. The numerical analysis of the raft frame and vibration isolation Changes in the parameters of the device affect the power flow to the infrastructure. The consistency between the analysis results and the results of admittance analysis and traditional vibration isolation theory shows that the analysis in this paper is correct.
