振动反馈主动控制的功率流计算方法研究

A method to calculate the vibration power flow in the feedback vibration control system

功率流是评价隔振效果的有效指标之一,但是如何计算主动隔振中的功率流实用方法仍然有限。有限元是工程上实用的方法,文中提出了在有限元分析基础上实现反馈控制的主动减振的功率流计算方法,并举例验证了计算方法的有效性。在此基础上还给出了优化设计方法,可作为主动控制设计参考。

Vibration power flow is an effective index for evaluation of vibration isolation effect. But there is not an applied method to calculate the vibration power flow in active vibration Control system. Finite element method is a widely used engineering method.In this paper, a method to calculate the vibration power flow in active vibration control by feed back control using finite element analysis was brought out and calculation examples were given, in which its validity was proved. The means to optimizing the parameters using such a method was also given. It could be good references to design of active vibration isolation system.
