摘要

以汽车变速箱顶盖为例

运用MAGMA软件

并结合正交试验

对汽车变速箱顶盖压铸工艺的充型、凝固过程进行了数值模拟。根据模拟结果

预测铸件在实际生产中可能产生的缺陷的种类、大小、位置及发生时间

提出工艺改进方案

确定最优工艺

同时进行试制。运用X射线实时成像技术对铸件缺陷进行验证。结果表明

MAGMA软件可以较为准确地模拟铸件的充型、凝固过程

并预判铸件缺陷的发生概率。

Abstract

With the help of simulating filling and solidification process

die casting process for the gearbox cover was optimized by MAGMA software and orthogonal test.Through simulation to predict possible defects type

size

location and time in practical production castings

process improvement program was conducted to determine the optimized process.During the process of the experimental trial

the casting defects was detected by using X-ray imaging system.The results show that MAGMA software can simulate more accurately filling and solidification process as well as predicting the probability of casting defects.
