采取ProCAST软件对ZL101航空壳体铸件的成形过程进行了模拟,对改进工艺后的铸件进行了的实际生产。结果表明,数值模拟能够直观地看到铸件的充型、凝固过程,准确地预测出可能产生的缺陷。铸造工艺设计及工艺优化,提高了铸件质量,降低了生产成本。 ProCAST software was used to simulate the forming process of ZL101 aviation shell castings, and the actual production of improved castings was carried out. The results show that numerical simulation can visually see the filling and solidification process of castings, and accurately predict the possible defects. Casting process design and process optimization, improve the quality of castings, reducing production costs.
