摘要
基于FEPG开发平台的元件化程序设计方法和代码生成技术,采用并行有限元自动生成系统PFEPG进行铸造过程数值模拟有限元程序的开发。开发了模拟铸件凝固过程中温度场变化、固相率场和铸件缺陷预测的铸造过程有限元数值仿真软件。与同类分析软件ProCAST的计算结果及试验测量结果进行对比,结果显示,所开发软件计算结果准确性及计算精度较高,铸件缩孔缩松预测结果基本准确,分析计算结果能满足工程实际应用。
Numerical simulation software for casting solidification process was developed by using componentized programming designing method and code automatic generation technology based on FEPG development platform.The software has the function of numerical simulation for temperature field and solid fraction distribution during casting solidification and can predict casting defects based on FEM method.By comparing the analysis results with those of a similar analysis from the ProCAST software and the experimental measurement data,it was found that the accuracy and precision of results coincided with each other.The analysis results can satisfy the practical application.
