摘要
液压流体脉动对液压系统的性能与可靠性影响很大。为了减小甚至消除液压流体脉动,各国学者在这方面做了大量工作,提出了各种主动及被动消振策略,取得了很好的消振效果。本文介绍液压流体脉动产生机理及危害、主动消振策略、目前的研究现状以及主要控制算法,提出了可能的研究方向,并对应用前景进行展望。
Hydraulic fluid fluctuation has great influence on the performance and reliability of hydraulic systems. To reduce and even eliminate fluid fluctuation, researchers in different countries have done a lot of work and proposed all kinds of active and passive vibration control strategies, and obtained better control effect. The mechanism and damage of hydraulic fluid fluctuation, active control strategies, present research actuality and main control algorithms were introduced, then possible directions of the research were put forward, and in the later future applications were prospected.
