摘要
首先对汽车差速器壳进行合理的铸造工艺方案设计,然后利用华铸CAE软件对球墨铸铁差速器壳的充型及凝固过程进行数值模拟。基于模拟结果,预测和分析在此工艺方案下铸件产生缩孔的倾向和形成原因,进而提出冒口补缩系统的优化方案,成功消除了差速器壳铸造过程中产生的缩孔缺陷。结果表明:利用CAE计算机模拟技术有助于为工艺方案的评估与优化提供可靠的借鉴,缩短了产品试制周期,降低废品率,保证了铸件质量。
A casting process of car differential case has been designed before InteCAST software was used for numerical simulation of the mould filling process and solidification process of ductile iron differential case. Based on simulation results, the tendency and cause of formation of shrinkage cavity in castings under this program have been forecasted and analyzed then the optimization program of riser feeding system was made, which was successful in eliminating the shrinkage defects which were generated during the casting process of differential case. The results indicated that the use of CAE computer simulation technology was helpful to providing appraisement and optimization of process program with dependable reference, shortening trial production cycle, reducing rejection rate hence ensuring the casting quality.
