摘　　要：运用Hyper Xtrude对某壁厚不均的工业铝型材挤压过程进行仿真模拟,获得了金属流动的速度场,分析了型材挤压时的变形情况。根据型材的流动变形情况对模具结构进行了优化,通过焊合阻流块以降低型材流速快的部位的流动速度,型材的"起浪"现象得到明显改善。上机试模结果表明,试模情况与模拟结果基本一致,基于Hyper Xtrude的数值模拟,预测实际挤压过程中可能出现的变形缺陷,对挤压模具设计和优化有很重要的指导意义。The extrusion processing of aluminum profiles with non-uniform wall thickness was simulated by using of HyperXtrude, and the field distribution of velocity of metal flow was obtained. According to the ductile deformation of the profile, the mold structure was optimized. It was showed that the production test results were in good agreement with the simulation. It confirms that numerical simulation based on HyperXtrude may successfully predict the potential deformation defects occurring in the actual extrusion process and is of great importance to provide theoretical basis for the design and optimization of extrusion die.
