本文介绍的反馈控制消振器,是—种基于反馈自动控制原理的机械振动抑制系统.它通过机械对象测得振动信号,来反馈控制具有外加能源为动力的阻振装置,使之产生阻振力来抑制原始的振动.这种反馈控制消振器的主要优点有:(1)它能在相当大的频率范围内使用,而没有动力减振器之类的调谐问题,因而能用于多振型、变参数或复杂振动成分的机械系统中点位抑制振动控制;(2)它是利用所测获的振动信息来控制外界能源,并能动地消除机械振动,其消振效果取决于增益,可控(?)调.所以消振效率也
The feedback control vibration absorber introduced in this paper is a kind of mechanical vibration suppression system based on the principle of feedback automatic control.It measures the vibration signal through the mechanical object to feedback control the vibration damping device with external energy as the driving force to make the vibration The main advantages of this feedback control damper are: (1) It can be used over a wide range of frequencies without tuning problems such as dynamic shock absorbers, and can therefore be used for more (2) It uses the measured vibration information to control the external energy source, and can eliminate the mechanical vibration dynamically. The vibration suppression effect depends on the gain , Controllable (?) Transfer, so the damping efficiency is also
