摘　　要：铣削薄壁零件时由于其系统的弱刚度属性极易发生变形和振动,本文基于磁流变液辅助支承通过变化电流控制结构刚度的属性,建立起了铣削系统动力学方程,并将系统刚度阻尼、磁流变液塑性力与控制电流分别建立起方程,利用Matlab/Simulink对其分别进行铣削仿真,得到不同电流波形输入下工件振动的加速度响应,以此总结成电流的模糊控制规则。最终通过铣削试验验证了该控制方案的有效性,获得了理想的减振效果,为铣削弱刚度零件提供了一种新型且有效的控制理论和技术选择。When milling thin-walled parts,due to the weak stiffness property of the system,deformation and vibration are extremely likely to occur.This paper,based on the magnetic fluid-assisted support,which can control the structural stiffness by changing the current,establishes the dynamic equation of the milling system.The system stiffness and damping,the plastic force of the magnetic fluid,and the control current are respectively established into equations.Using Matlab/Simulink,milling sim-ulations are conducted respectively,and the acceleration response of the workpiece vibration under different current waveforms is obtained.Based on this,the fuzzy control rules of the current are summarized.Finally,the effectiveness of the control scheme is verified through milling experi-ments,and an ideal vibration reduction effect is achieved,providing a new and effective control theory and technology option for milling parts with weak stiffness.
