Abstract：

Based on a tracking water-cooling program written by APDL language, a 3D mobile tracking water-cooling full coupled model of electromagnetic-thermal-stress was established by the finite analysis software adopting magnetic field and temperature field coupling moving heat source, and then the tracking water-cooling and natural air cooling in the process of high frequency induction heating forming were numerical simulated and analyzed in experiment. The rationality of the model was verified by comparing the results of measurement with numerical simulation, and the influences of different cooling methods on forming steel plate were analyzed. The results show that the distributions of both the temperature field and Y direction stress field are uneven, the plate is of the greater temperature gradient in the condition of tracking water cooling, and the amount of displacement along the Y direction and bending angle are greater than that in the natural air cooling condition, of which the average increase of displacement along the Y direction is 0.45 mm, and the average increase of bending angle is 0.5°.
