摘要
利用铸造模拟软件Easycast,采用重力铸造和低压铸造两种不同铸造工艺对铝合金轮毂进行充型、凝固模拟分析。通过模拟获得了两种工艺下的流动场和凝固场结果,对缺陷进行了预测分析,得到了轮毂件重力铸造与低压铸造方法优劣的差异,用实际证明了计算机模拟在铸件工艺优化过程中的优越性。
The processes of mold filling and solidification process of the aluminum alloy wheel hub in gravity casting and low-pressure casting were simulated by using the casting simulation software Easycast. Through the simulation, two kinds of flow field and solidification field were obtained. And the defects were forecasted. The advantages and disadvantages between gravity casting and low-pressure casting of the wheel hub were gotten. The advantage of computer simulation in optimization process of casting technology was proved by fact.
