【摘要】 电流变液是表观粘度随外加电场变化的一种胶质悬浮液。基于此良好的机电耦合特性 ,附加电流变液的减振器为在机械系统与结构中引入半主动控制技术提供了最佳的手段。本文介绍了电流变液、电流变效应和电流变液减振器的工作方式 ,并结合国内外的研究现状对应用于切削颤振控制领域中的电流变液减振器进行了综合评述。最后 ,对目前制约电流变液减振器应用的因素也进行了讨论。更多还原

【Abstract】 Electrorheological fluid (ERF) is a kind of colloidal suspension whose apparent viscosity is variable in response to the strength of electric field.Based on this property,the electrorheological fluid vibration dampers offer an elegant means of introducing semi-active vibration control to machines and structure.In the paper,the electrorheological fluid,the ER effect and the modes of operation of ERF vibration damper are expounded;the comprehensive survey of incorporating research of ER device for machining chatter control at home and abroad is provided and the factors hampering the application of ERF vibration damper are discussed.更多还原
