差速器壳体高压压铸工艺模拟及优化
Numerical Simulation and Optimization of High Pressure Casting for Differential Housing
摘要
Abstract
The study aims to address the prevalent challenges of blowhole and shrinkage during the high-pressure casting of aluminum alloy differential housing.A comprehensive numerical simulation was carried out utilizing the finite element software ProCAST.The simulation comprised of a solution of the flow field,temperature field,and velocity field to predict potential casting defects.To optimize the casting process,an orthogonal experimental design was employed.The simulation results indicated the existence of spiraling issues at the bottom cylinder and both sides of the support during the filling stage.Additionally,the high metal temperature gradient during solidification led to uneven solidification,premature solidification at the gate,and shrinkage defects upon complete solidification.By considering the impact of casting parameters on solidification time,spiraling volume,and shrinkage volume,the optimal casting parameters were determined to be a pouring temperature of 650℃,a mold temperature of 220℃,and a shot speed of 5 m/s.Finally,a casting experiment was conducted to verify the reliability of the determined casting parameters.关键词
