摘　　要：拨叉件是汽车变速器上的重要零件,一般采用熔模精密铸造工艺进行生产,热裂是拨叉件生产中常见的铸造缺陷。本文通过分析热裂产生的机理,采用相当热节计算法设计浇注系统,并进行数值模拟,计算了铸件的流场、温度场和应力场,模拟结果准确性得到了实验验证。Fork part is one of the important parts, the common process is precision casting for fork, cracking is a common casting defect in precision casting. In this paper, by analyzing the mechanism of hot cracking, hot section method is used to design the pouring system, the fluid field, the temperature field and the stress field are simulated and calculated, the accuracy of the simulation result is verified.
