摘　　要：根据磁流变液在梯度磁场作用下发生剧变的特点,以流体动力学理论为基础,对Preston方程、Reynolds方程及其边界条件进行扩充,建立了在二维方向上的磁流变光整加工的压力模型和材料去除数学模型,并对该模型进行仿真分析。最后进行磁流变光整加工的基础实验,分析了不同的工件压入量和材料类型对材料去除率的影响,通过将实验结果与材料去除模型的仿真结果进行比较,以验证该模型的合理性。According to the theological characteristics of magneto--theological fluid in the magnetic field, the Preston equation, the Reynolds equation and its boundary conditions were extended based on fluid kinematical theory. The pressure model and the material removal model in two--dimensional directions were built and analyzed. Finally,the basis experiments of MRF were carried out,and the influences of the immersed depth and material types were studied. The experimental data were compared with the simulation results of material removal model,which confirms validity of the model.
