基于数值模拟的电机壳体铸造工艺的优化设计

Optimal Design of Casting Process for Electrical Engine Shell Based on Numerical Simulation

为消除湿型铸造工艺生产球铁铸件出现缩松、缩孔等缺陷,设计了5种电机壳体球铁铸件铸造工艺,并采用华铸CAE对其进行仿真分析,预测其缩松、缩孔缺陷的位置与大小,获得了最优的铸造工艺方案。

To eliminate shrinkage defects in conventional wet casting process to produce ductile iron castings, five types of casting processes for electrical engine shell of ductile iron were designed, and the processes were simulated and analyzed using Huazhu CAE to forecast the position and size of shrinkage defects, the optimal casting process was obtained.
