偏心激励作用柔性主被动隔振系统功率流特性

Power Flow and Active-Passive Isolation of a Flexible System Excited by an Off-Center Force

针对柔性基础上偏心激励作用复杂机械系统 ,建立了机器 -柔性板基础主被动隔振系统数学模型 ,推导了系统动态特性传递方程。以传递到基础的功率流为评价指标 ,探讨不同激励及主动控制策略对主被动混合隔振效果的影响。

In this paper, a theoretical model for vibrating machine excited by an off-center force and isolated from non-rigid substructure by passive-active isolators is proposed, and the dynamic analysis method is developed to predict the power flow characteristics in coupled system. Based on them, numerical calculations of power flow for practical mechanical systems are carried out to explore the effect of different excitation forces and active control strategy on power flow.
