摘　　要：多层隔振系统是隔振降噪一项重要的技术,而功率流方法是评价隔振系统隔振效果的有效方法。基于多层隔振系统建模理论,推导了多层隔振系统的功率流传递公式,并详细讨论了多层隔振系统上下层隔振器刚度、阻尼比及中间质量对功率流传递的影响。Multi-stage vibration isolation system is important technique in vibration and noise isolation field.Power flow analysis is also important method to evaluate systems isolation effectiveness.Based on dynamic equation of multi-stage vibration isolation system,the power flow transfer expression was derived in this paper.The parameter influence,including stiffness and damping ration of upper and lower isolator and the middle mass,on multi-stage vibration isolation systems power flow transfer characteristics was discussed.
