在Deform开放子程序基础上对其进行了二次开发,通过程序算法等效了实际温控系统的功能,从而实现对超塑成形设备加热平台进行升温全过程的数值模拟。其中温度场模拟的关键还包括对实际设备的简化模型处理,以及可靠热物理参数的输入等。通过多次分析模拟计算,显示加热孔的分布对加热平台的温度均匀性影响较大。通过对加热孔分布的设计优化与数值模拟结合,得到了最佳的加热孔设计方案,验证了二次开发程序的可靠性;通过多次分析模拟计算结果对加热平台的温度均匀性设计做出评估,并成为不断优化加热平台设计改进的依据。
Based on the Deform open subroutine, it has been developed for the second time, and the function of the actual temperature control system is equivalent through the program algorithm, so as to realize the numerical simulation of the heating process of the superplastic forming equipment heating platform. Among them, the key of the temperature field simulation is to simplify the model processing of actual equipment, and to input the reliable thermophysical parameters. Through multiple analysis and simulation calculation, it shows that the distribution of heating holes has a great influence on the temperature uniformity of the heating platform. Through the optimization of heating hole distribution and numerical simulation, the best heating hole design scheme is obtained, and the reliability of the secondary development program is verified. The temperature uniformity of the heating platform is designed through multiple analysis and simulation results Assessment, and continue to optimize the heating platform design basis for improvement.
