摘要
电流变技术是电流变现象或电流变效应在工程实践中成功应用的一门技术,为了提高数控车床的加工精度,在分析了数控车床振动特性的基础上,设计了一种基于电流变液的数控车床刀具减振器,应用于抑制切削振动和振动控制。由于电流变液快速、可逆固液化以及易于控制的特性,为了能将数控车床上的振动量减少一个数量级,可以通过选择合理电流变液阻尼器的相关参数和正确设计振幅实时控制系统的方法,从而满足对数控车床减振的要求。
Electrorheological technology as electrorheological phenomenon or electrorheological effect was a technology which successfully applied in engineering practice,in order to improve the machining accuracy of CNC lathes,based on the analysis of the vibration characteristics of CNC lathes,it was designed that a kind of CNC lathes tool shock absorber based on electrorheological fluid,which was applied to restrain cutting vibration and vibration control.Due to the characteristics of fast,reversible and easy control of electrorheological fluid,in order to reduce the vibration on CNC lathes by an order of magnitude,we chose reasonable parameters of electrorheological fluid damper and designed the method of amplitude real-time control system correctly,so as to meet the requirements of vibration reduction on CNC lathes.
