摘　　要：针对工程中弹性基础引起动力设备的振动和噪声控制问题,建立了多支承弹性隔振系统的动力学模型,推导了机器、隔振器和弹性基础之间的动态传递方程,以能量传输观点来评价系统隔振效果,揭示机组、隔振器刚度,以及基础刚度等的不同参数对功率流的影响,为工业设计时参数的选择提供参考。The equipment vibration and noise, which is caused by a machine on the flexible foun- dation in engineering, is studied on dynamic model of multiple mountings isolation system. The dynamic transfer equations are deduced, which are composed of the machine, isolators and elastic foundation. From the point of view of energy transmission, the aim is to discover influence of different parameter of set, isolators stiffness and foundation stiffness so that reference is provided for industrial design parameters.
