对于双层隔振器，作动器的位置直接影响其主动隔振效果。在作动器性能理想的情况下，以不同放置方案所能达到的最优性能为评价指标，利用功率流方法研究了双层隔振器的被动部分参数对作动器放置位置的影响。针对双层隔振器两种作动器放置方案进行了理论推导和仿真分析。仿真结果表明：当放置于中间质量块与基础平台之间的阻尼系数大于放置于中间质量块与隔振对象之间的阻尼系数时，或者中间质量块质量比基础平台质量小时，或者当放置于中间质量块与基础平台之间的刚度系数和放置于中间质量块与隔振对象之间的刚度系数相差很大时，作动器应放置在中间质量块与隔振对象之间；其它情况下应放置在中间质量块与基础平台之间。

The location of actuator in double-layer vibration isolator directly affects the isolation performance.The optimal performances for each placement scheme were taken as the criteria and the method of power flow was made in use to study the effect of passive parameters in the double-layer vibration isolator on the actuator location.The theoretical derivation and simulation analysis were carried out for two possible actuator locations.The results show that:the actuator should be located between the middle mass and the isolation mass when the damping coefficient between the middle mass and the base mass is larger than that between the middle mass and the isolation mass,or when the middle mass is smaller than the base mass,or when the two stiffness coefficients differ greatly.For other conditions,the actuator should be located between the middle mass and the base mass.
