摘　　要：为了获得力学性能优良的电机支架铸件,分析了其离心铸造成型原理。运用有限元软件AnyCasting建立了电机支架离心铸造成型仿真模型,对离心铸造成型过程中的钢液流动速度、温度随离心铸造时间的变化趋势进行了有限元仿真分析。对充型100%时铸件碳偏析分布进行了有限元分析。结果表明:在电机支架离心铸造成型过程中,铁液在自身重力及离心力作用下,由下往上不断充型;在不同离心铸造阶段,铁液流动速度及温度分布不同,且最大值主要分布在浇注口、壁厚较厚及实心部位。In order to obtain the motor support casting with excellent mechanical properties, the principle of its centrifugal casting was analyzed. The simulation model of centrifugal casting of the motor bracket was established by using the finite element software AnyCasting. The variation trend of the flow velocity and temperature of molten steel in the process of centrifugal casting with the simulation time of centrifugal casting were analyzed by finite element simulation. The finite element simulation analysis of carbon segregation at 100% filling was carried out. The results show that during the centrifugal casting of the motor support, molten iron is continuously filled from bottom to top under the action of gravity and centrifugal force, and the distributions of flow velocity and temperature of the molten iron are different in different centrifugal casting stages, and the maximum values are mainly distributed in the gate, thick wall and solid parts.
