| 摘 要： | 为了研究偏心激励下非对称双层隔振系统的功率流特性，建立了在偏心激励下，基座简化为梁的4自由度非对称双层隔振柔性系统的动力学模型。通过对其实例的数值分析和计算，得到了输出功率流的频率谱曲线，并通过研究不对称参数对功率流响应的影响，得出了对应不同位置的偏心激励应采用不同的不对称参数使系统传递的功率流最低的结论。

| Abstract: | In order to study the power flow properties of an asymmetric two -stage vibration isolation system with an off-center force , it simplifies the foundation as a beam , develops the dynamical model of a 4 degree-of-freedom asymmetrical two -stage vibration isolation system with an off -center force .Based on analysis of nu-merical example , it obtains the frequency spectrum , describes the influence of asymmetric parameters to power flow response .The result shows that the smallest power flow response is dependent to appropriate asymmetric pa -rameters and appropriate off -center ratio of exiting force . |
