摘要：

采用加热装置对热冲压模具进行温度分区，使同一零件的不同区域具有不同的冷却速率，最终得到同一热冲压成形件具有梯度性能的方法，是一种有效的热冲压工艺。以S梁为研究对象，利用Ls-dyna仿真软件，基于modeFrontier优化平台，采用Kriging模型的多目标遗传算法，以模具初始温度、板料初始温度、保压时间为输入变量，以板料最终温度、板料厚度和减薄率为目标函数进行优化，获得合理、有效的工艺参数为：B1500HS硼钢的初始温度为900 ℃、加热区凸模初始温度为500 ℃、加热区凹模初始温度为520 ℃、非加热区凹凸模初始温度为30 ℃、保压时间为5 s。最后，采用优化后的工艺参数对性能梯度分布热冲压工艺过程进行仿真，验证了优化结果的可靠性。

The heating device is used to partition the temperature of the hot stamping mold to make the different areas of a part have different cooling rates and finally obtain a method of the same hot stamping part with gradient performance, which is an effective hot stamping process. Then, for the S-beam, based on the modeFrontier optimization platform and the multi-objective genetic algorithm of Kriging model, taking the mold initial temperature, the sheet initial temperature and the time of pressure maintaining as input variables and the final temperature of sheet, the sheet thickness and the thinning rate as objective functions, the optimization process was conducted by Ls-dyna simulation software, and the reasonable and effective process parameters were obtained with the initial temperature for B1500HS boron steel of 900 ℃, the punch initial temperature of 500 ℃ in heating zone, the die initial temperature of 520 ℃ in heating zone, the punch and die initial temperature of 30 ℃ in non-heating zone and the time of pressure maintaining for 5 s. Finally, the optimized process parameters were used to simulate the performance gradient distribution of hot stamping process, and the reliability of optimization results was verified.
