摘　　要：以试验测得的温度为基础,基于Isight平台,结合数值模拟方法和模拟退火算法的优化方法,计算求解了A356铝合金铸件冷却凝固过程中铸件与金属铸型间的界面传热系数。采用优化软件Isight集成铸造仿真软件ProCAST,成功解决了这两个软件的接口问题,而且在后处理数据的提取方面,采用均匀步长的计算,与整理后均匀时间步长的试验数据能更好的匹配,从而方便计算优化目标。另外,它不仅可以准确计算出随温度或时间变化的传热系数,而且还可以应用该方法优化铸造工艺和模具。The interfacial heat transfer coefficient (IHTC) between castings and metal mold during solidification process was calculated through coupling numerical simulation with simulated annealing algorithm based on Isight platform by help of tested temperature data from A356 aluminum alloy. Meanwhile, interface input between the Isight and the ProCAST was resolved successfully. Uniform-step was used to calculate post-treated data, which was more matched with uniform time-step treated experimental data, Furthermore, it was convenient for calculating optimized goal. Through Isight platform integrating with ProCAST software, not only heat transfer coefficient with interface temperature or time can be accurately calculated, but also the method is used to optimize casting process and mould design.
