摘　　要：以某空心异形铝型材为研究对象,设计了挤压分流模。基于Hyperxtrude软件对挤压过程进行模拟,得到了铝型材挤压模具变形分布和等效应力分布。基于模拟结果对挤压工艺参数进行了正交试验设计和优化。结果表明,模具的等效应力降低了。结果可对异形空心铝型材挤压模具设计和工艺参数选择提供参考。Taking a hollow special-shaped aluminum profile as the research object, the extrusion die with split-flow was designed. The extrusion process was simulated based on the Hyperxtrude software. The deformation distribution and the equivalent stress distribution of aluminum profile extrusion die were gotten. The orthogonal experimental design and optimization were carried out for the extrusion process parameters based on the simulation results. The results show that equivalent stress of the die is reduced. The results can provide reference for hollow special-shaped aluminum profile extrusion die design and process parameters choice.
