基于FEM的法兰挤压铸造工艺设计及数值模拟

Process Design and Numerical Simulation of Squeeze Casting Flange Based on FEM

为了得到高品质的挤压铸造AlSiMgMn铝合金减速机用法兰,节约设计成本,使用有限元方法(FEM)对其挤压铸造过程进行模拟分析,根据预测的缺陷位置设计浇注系统,并对设计结果进行二次模拟,分析工艺设计的合理性。最后,通过试验验证模拟分析结果的可靠性,确定了法兰挤压铸造工艺方案,为批量生产提供参考。

In order to obtain high-quality flange for reducer and save design cost,Finite Element Method(FEM)was used to simulate the squeeze casting process.The gating system was designed according to the predicted defect position,and the design result was simulated again.The rationality of process design was analyzed,and the reliability of simulation analysis result was verified by experimental test to determine the optimized scheme,which could provide a reference for mass production.
