摘　　要：针对轮毂工业结构设计特点,应用ProCast软件对铸件的重力铸造、压铸成形方式进行了CAE仿真对比分析。结果发现,铸件的内圈结构限制了其采用重力铸造的可行性,因其在内圈和边缘将产生较多的缩孔、缩松。经过浇注系统改进后,采用压铸方式能将重力铸造过程中出现的缩松、缩孔问题得到有效解决。依据压铸CAE结果,设计了相应的压铸模具,模具结构简单实用。According to the structural characteristics of wheel hub,the comparison of gravity casting and die casting forming methods was carried out by ProCast software.The results show that the inner ring structure of castings limits the feasibility of using gravity casting,because of the presence of many shrinkage holes and porosity in the inner ring and edge.After the improvement of the casting system,the shrinkage and porosity in the gravity casting process are effectively solved by using the die-casting method.According to the CAE result of die casting,the die is designed with simple and practical structure.
