双边浇工艺铸造铝合金车轮的研究及优化

摘要

低压双边浇是一种制作铝合金车轮的新兴铸造方法,与低压中心浇进行了详细对比,结果表明两者在铸件的凝固顺序上有着本质的区别,并且双边浇工艺的特殊凝固顺序使其生产的汽车车轮的轮辐性能非常优良.作为一种新兴铸造工艺,本身存在一些不足需要不断改善优化,运用模拟分析对其中的铸造飞边问题进行重点攻关改善,并取得了较为理想的效果.%Low pressure bilateral pouring is a newly developing casting method for making aluminum alloy wheel,and detailed compared with low pressure centre pouring.The results show that there is an essential difference between the solidification sequence of the casting and the special solidification sequence of the bilateral pouring method.Product performance of automobile wheel spokes made by latter method is very excellent.As a newly developing method of casting,there are some problems that need to be continuously improved and optimized.And the problem of casting joint flash is solved by using of simulation analysis,which achieves better results.
