摘要

以汽车用铝合金排水管倾转铸造作为研究对象

运用AnyCasting软件对铝合金排水管铸件在重力下及倾转条件下的充型、凝固过程进行了数值模拟。通过对模拟结果数据进行定量分析

发现对于结构较为复杂且长度与厚度比差值较大的薄壁铸件

与重力浇注相比

倾转浇注具有较低且平稳的充型速度、充型压力自下而上分布均匀、排气效果好、卷气以及缩孔倾向小等特点

大大提高了铸件质量以及工艺出品率。

Abstract

Filling and solidification of aluminum alloy drain pipe for automobile in tilting casting and in gravity casting were predicted by the Anycasting software. Simulated results were analyzed quantitatively. The results reveal that

for thin-walled drain pie with complex structure and large ratio of length via thickness

compared with gravity casting

tilting casting exhibits the features of lower and smooth filling velocity

uniform distribution of filling pressure from bottom to top

desirable exhausting effects and lower entrapped-gas and shrinkage porosity tendency

greatly improving the quality of the parts and production yield.
