摘　　要：在对A356铝合金汽车轮毂热处理工艺分析的基础上,采用ANSYS有限元软件对铝合金汽车轮毂淬火过程中温度场及热应力场的分布进行数值模拟与分析。研究表明:在淬火过程中,轮毂在47 s时完全冷却到70℃,与实际较为吻合。轮毂受到的最大热应力为180.507 MPa,小于A356铝合金的强度极限。轮毂在淬火过程中会发生微量的变形,距离轮辐最远处的变形量最大,其值为0.127341 mm,建议在热处理后对汽车轮毂进行精密校核。The temperature and thermal stress fields of Al alloy automobile hub in the quenching process were simulated and analyzed by FEM analysis software（ANSYS）,based on analyzing the heat treatment process of the A356 Al alloy automobile hub.The results show that the hub is cooled to 70 ℃ at 47 s in the quenching process,which is consistent with the practical situation.And the maximal thermal stress is 180.507 MPa,which is less than the strength limit of A356 Al alloy.Tiny deformation appeares in the quenching process,and the maximal value that appears in the furthest away the spoke is0.127341 mm,so that it is advised that the close checking is done for the automobile hub after heat treatment.
