摘　　要：基于ProCAST数值模拟网格文件,提出了一种精铸模具反变形方法。首先提取所需网格文件中节点信息,将无序节点进行匹配变为有序节点。网格文件简化法与快速排序法的结合提高了排序匹配的效率。建立了模具反变形系统,经验证,所采用的方法取得了良好的效果。Based on the numerical simulation results of ProCAST, an reverse deformation method for investment casting die is presented. The node information is extracted first, and the disordered grids are changed into order ones. The efficiency of sorting and matching can be improved by the combination of the methods which are used for the simplification of grid files and quick sort. And the reverse deformation system of die is built. The example proves the better effect on die design of turbine blade.
