摘要
介绍了差速器壳体铸件的结构、技术要求以及原来采用的铸造工艺。借助JMatpro软件设计出铸件的化学成分,并借助MAGMA数值模拟软件对原工艺方案的铸件凝固过程进行了模拟,发现多处可能产生缩松缺陷。根据模拟发现的缩松位置,改进了铸造工艺,使缩松缺陷得以消除。
The configuration,technical requirements and the original casting method of the differential case were introduced.By using software JMatpro,the chemical composition of the casting was designed and,by using software MAGMA,the casting solidification process of original casting method was simulated and it was revealed that there would be shrinkage porosities occurring in multiple places.Based on the shrinkage porosities locations found by simulation,the casting method was improved and as the result,the shrinkage porosities were eliminated.
