铝合金活塞铸造过程中低压铸造工艺的有限元模拟研究

Finite element simulation of low pressure casting process for aluminum alloy piston casting process

低压铸造工艺是通常情况下铝合金活塞的铸造中的核心工艺技术之一,想要进一步提高铝合金活塞制造质量,需要对低压铸造过程进行更加精准的掌控。通过ANSYS软件建立铝合金活塞的几何模型,运用网格划分将几何模型转化成有限元模型,设置相关低压铸造参数,在软件中进行低压铸造工艺的有限元模拟,完成有限元模拟方法设计,并设计实验对方法有效性进行了论证。

Low pressure casting is one of the core technology in the casting of aluminum alloy pistons. To further improve the manufacturing quality of the aluminum alloy piston, it is necessary to control the process of low pressure casting more accurately. The geometric model of the aluminum alloy piston is established by ANSYS software. The geometric model is transformed into a finite element model by the grid division. The relative low pressure casting parameters are set up. The finite element simulation of the low pressure casting process is carried out in the software. The finite element simulation method is completed, and the validity of the method is demonstrated by the design test.
