| 摘 要： | 综合运用统计能量分析(SEA)理论和功率流方法,建立了多方向激励作用下的侧向悬挂双层隔振系统的统计能量分析模型,对其功率流传递率进行了仿真分析,同时进行了侧向悬挂双层隔振系统的功率流实验,测量了其在多方向激励作用下的功率流传递率,将统计能量仿真计算结果与功率流实验结果进行了对比,结果表明两者的功率流传递率在中高频段基本一致,传递到基础的侧向功率流大于垂向功率流,侧向振动在侧向双层隔振系统中不能被忽略。

| Abstract: | Statistical energy analysis(SEA)theory and power flow method were used to establish the SEA model of lateral suspended two-stage vibration isolation system,and then the power flow transfer ratio of vibration isolation system were simulated and analyzed.Meanwhile power flow test in lateral suspended two-stage vibration isolation system is done to measure the transfer ratio of the power flow under multi exciting forces.The comparison results between simulating and experiment show that the simulating results a... |
