摘　　要：为抑制外圆车削振动,设计了基于挤压模式的磁流变液车刀减振仪。在其结构和零件材料已确定的基础上,通过电磁学理论,利用Ansoft Maxwell对不同结构参数组下减振装置内的磁感应强度进行了三维磁场仿真分析,总结了不同参数组对磁感应强度的影响规律,获得了理论上的最大磁感应强度,并据此确定了外圆车刀减振仪的结构。To suppress turning chatter,a reducing vibration device based on MRF for turning tool was designed.Based on magnetic circuit theory,the structure and the magnetic strength of the damping device was analyzed by simulation with Ansoft Maxwell under different materials and structural parameters.The influences of the main parameters on the magnetic strength were summed up,the main parameters of the device were decided,and the magnetic induction of the MRF damping device was determined theoretically.
