- 摘要:
- 针对商用车铝合金轮毂在铸造时出现的缩松、气孔等缺陷进行机理分析和原因推断，并采用 AnyCasting 软
件对铝合金轮毂低压铸造过程进行了模拟分析；针对充型卷起、充型氧化物、粒子追踪、凝固顺序等方面可能形成的缺
陷进行了模拟，分析了法兰盘缩松形成的原因；针对法兰盘缩松缺陷位置、分布情况、产生原因制定了相应的预防措施，
优化了铸造工艺。 结果表明，经过试制检测，利用优化后的工艺可以消除铝合金轮毂常见缺陷，轮毂品质优良。
The mechanism analysis and reasons were carried out for the defects such as shrinkage and porosity in casting of
aluminum alloy wheels of commercial vehicles. Simulation analysis was carried out for the low-pressure casting process of
aluminum alloy wheels by using AnyCasting software. The possible defects in filling roll, filling oxide, particle tracking and
solidification sequence were simulated, and the causes of flange shrinkage were analyzed. According to the position,
distribution and cause of shrinkage defects of flange, the corresponding preventive measures were formulated and the
casting process was optimized. The results show that the common defects of aluminum alloy wheel hub can be eliminated
by using the optimized process, and the wheel quality is good.
