摘　　要：针对某一大悬臂铝合金型材,在分析铝合金型材挤压模具各结构要素的基础上,设计了带有导流室结构的模具并对其进行了强度校核;运用绘图软件建立了模具的三维仿真模型;基于Hyper Xtrude有限元分析软件平台,对该型材的挤压过程进行了模拟仿真分析,获得了挤压过程中模具的应力和变形分布。通过对模拟结果的分析,预测了挤压时可能产生的模具变形、裂纹等缺陷,并对模具结构进行了优化设计,保证了挤压型材的尺寸精度和模具的使用寿命。With regard to the extrusion die of an aluminum profile with large cantilever, a die structure with diversion chamber is designed and the strength is checked based on the analysis of each structure element of the extrusion die. 3 D simulation model of the die is built with the mapping software. The stress and deformation distribution is obtained through the simulation analysis on the extrusion process based on the HyperXtrude finite element analysis software platform. The defoiTnation of die, cracks and other defects in the process of extrusion are predicted through analysis of simulation results. The die structure is optimized, ensuring the life of the die and the size accuracy of the profile in extrusion.
