摘　　要：基于电磁相互作用原理,将三相异步电动机的转子抽去,代之以永磁式转子磨具。在电动机接入三相交流电后,利用电动机定子所产生的旋转磁场来驱动永磁式转子磨具旋转,从而实现对不锈钢管内壁的光整加工。结合试验所得实测参数,借助Ansoft软件对磁性珩磨系统进行建模与仿真分析。通过理论计算与仿真结果的对比,验证了光整加工试验的可行性。之后对三种不同材料的珩磨条,在不同转速以及是否加冷却液的情况下分别进行试验。通过对比加工后试件内壁的表面粗糙度,得出上述三个因素各自对不锈钢管内壁光整加工效果的影响关系,为不锈钢管内壁光整加工工艺参数的选取提供参考。Based on the principle of the interaction between the electric and magnetism, subducted the three-phase asynchronous motor＇s rotor, and replaced it with permanent magnetic abrasive rotor. After the motor energized with three-phase alternating current, using the motor stator＇ s rotating magnetic field to drive the permanent magnetic abrasive rotor, so as to realize the inner surface of stainless steel pipe ＇ s finishing. With the actual parameters we got in the experiment, modeled the magnetic honing system and conducted simulated analysis by using Ansoft. Through the comparison between theoretical calculation and analysis results, verified the feasibility of the finishing experiment. Then we conducted experiments separately among three different materials of honing stone, at different speed and whether to add cooling fluid. Then compared their inner surface＇ s roughness value, and obtained how the three factors influenced the finishing effect of the stainless steel pipe＇ s inner surface separately, which will provide a reference for the selection of process parameters in the finishing of the stainless steel pipe＇ s inner surface.
