摘要
切削颤振是降低细长轴类零件加工质量的主要原因,为此本文研制了用于车床刀架的磁流变减振装置。在结构设计的基础上,本文对减振装置的磁路进行了理论分析,并利用有限元方法对减振装置进行了三维磁路仿真,研究了不同结构参数对减振装置中磁感应强度的影响规律,获得了符合设计要求的磁流变减振装置。本文研究可为同类磁流变减振装置的优化设计提供依据。
Cutting chatter is the main reason resulting in lower machining quality of slender shaft parts.In this paper a magnetorheological damping device for lathe tool slide was developed.On the basis of structural design the magnetic circuit of the damping device was analyzed theoretically,moreover,the three-dimensional magnetic field was simulated with finite element method,the effects of different structural parameters on the magnetic induction intensity of damping device were investigated.Finally,the magnetorheological damping device which meets the requirements was obtained.The researches in this paper provide the foundation for optimized design of similar magnetorheological damping devices.
