摘　　要：研究了显像管玻壳成形过程中温度场集成冷却模拟方法,开发了工艺参数和模具冷却结构优化系统.该系统利用有限差分法,在厚度方向上对玻壳采用局部的一维瞬态分析,运用三维边界元方法模拟模具的三维热传导,玻壳和模具通过耦合分析来匹配型腔表面的温度和热流量.研究表明,所提出的集成和耦合数值模型模拟结果与实验结果吻合良好.An integrated cooling simulation method for the temperature field of the panel during the forming process was proposed.The simulation system for the optimization of processing parameters and in-mold cooling system structure design was developed.A finite-difference method based local one-dimensional transient analysis in the thickness direction is adopted for the panel part.A three-dimensional,boundary element method is used for the numerical implementation of the heat transfer analysis in the mold region.The part and mold analysis are coupled so as to match the temperature and heat flux on the glass-mold interface.This paper presented an integrated and coupled numerical model for analyzing the panel cooling process.The numerical results are in good agreement with the experimental ones.
