摘要
针对电流变阻尼器抑制切削颤振存在的困难,设计了一种流动与剪切混合模式的电流变阻尼器。介绍了电流变液及电流变阻尼器的工作原理和性能特点;基于B ingham塑性理论,建立了流动与剪切混合模式的电流变阻尼器的力学模型。实验与仿真结果表明,电流变阻尼器能很好地实现振动的实时控制,并能有效地抑制切削颤振的发生。
Facing the difficulty that ER fluid damper contains the cutting chatter,we designed a damper based on flow and shear mixed model to control the cutting chatter.This paper introduces the principle and ER fluid damper,founds the mechanical model of ER fluid damper of flow and shear mixed model based on Bingham plastic theory.The result of experiment and simulation shows this ER fluid damper can well control the vibration and the cutting chatter.
