摘　　要：磁场发生器在加工长不锈钢管过程中温升较大,限制了磁性珩磨技术的推广应用。对此,文章提出了外循环水冷的冷却方法,在Pro/E中建立仿真模型,采集无水冷时的实验数据并导入到Origin中拟合出符合温度随时间变化的数学方程,然后将ANSYS Steady-State Thermal和ANSYS Fluent有限元分析软件进行耦合;加载发热源和外部水冷条件求得该系统稳态温度分布云图。结果表明:运行12000s(3.33h),系统达到热平衡,其瞬态最高温度为55℃,而无外循环水冷稳态最高温度为75℃,延长了电机的使用寿命,达到了冷却目的,为可持续磁性珩磨加工提供理论依据。The process of magnetic field generator temperature rise is larger,limits the popularization and application of magnetic honing technology,To this,this article puts forw ard the outer circulating w ater cooling method,simulation model is established in the Pro/E model,w ithout w ater cooling experiment data and imported into the Origin of fitting out mathematical equations of temperature change over time,then import into ANSYS Workbench,Steady-State and ANSYS Thermal and finite element analysis softw are ANSYS Fluent coupling; Loading heat source and external cooling conditions obtained nephogram of temperature distribution in the system. Results show that the running 12000 s( 3. 33 h),the system to achieve thermal equilibrium,the steady temperature is 55 ℃,w ithout external loop w ater-cooling the steady state highest temperature is 75 ℃,extend the service life of the motor,to achieve the cooling,for magnetic honing system processing and provides the theory basis for sustainability.
