摘要：

基于APDL语言编写了跟踪水冷程序。采用磁场与温度场耦合移动热源，运用有限元分析软件建立了三维移动式跟踪水冷的电磁-热-应力的全耦合模型，对高频感应加热成形中跟踪水冷和自然空冷进行了数值模拟和实验分析。并利用实验测量结果和数值模拟结果证明了模型的合理性；分析了不同冷却方式对钢板成形的影响。结果表明：钢板加热时温度场和Y方向应力场分布都不均匀，且在跟踪水冷条件下钢板获得更大的温度梯度，其最终沿着Y方向的位移量和弯曲角度均大于空气自然冷却条件下沿着Y方向的位移量和弯曲角度。其中沿着Y方向的位移量平均增大0.45 mm，弯曲角度平均增大0.5°。

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°.
