Abstract: Aiming at the problems of serious heating and unsustainable processing of electromagnetic magnetic honing system, the loss of magnetic honing system, temperature field model and air cooling system were studied. The equivalent simulation model of electromagnetic magnetic honing system was established, and various losses generated by the system were analyzed and calculated. Based on heat transfer theory, the steady temperature field of magnetic honing system was simulated and analyzed by finite element method, and the temperature rise variation curve of the system was obtained. A set of air cooling system was designed. Based on the knowledge of fluid mechanics, the wind speed at the air outlet was obtained. The wind speed was converted into heat dissipation coefficient, and the temperature rise characteristics of the magnetic honing system under air cooling were obtained. Finally, the temperature rise experiment of the electromagnetic magnetic honing system was carried out, and the accuracy of the calculation method was verified by comparing the experimental results with the calculation results. The results indicate that the maximum temperature of the electromagnetic magnetic honing system reaches 59.3° at steady state under the working condition of 600 r/min and the air cooling device is added, and the system can work stably.
