摘　　要：在MSC Superforge有限元分析软件平台上,采用有限体积法在3种不同导流模情况下,对薄壁“一”字形铝型材的挤压过程进行了数值模拟,分析了变形过程的力学特点与变形规律,通过对挤压实验结果的比较,理论结果与实验结果基本一致,而实验结果也对导流模的优化设计有着直接的指导意义。Based on the platform of MSC Superforge finite analysis software, the typical extrusion process of thin-wall aluminum profile was simulated with finite volume method （FVM） under three kinds of flow-guilding molds. The mechanical features and deformation rules of the process was analyzed in details. The results of the simulation were agreeable to general extrusion principles, which can favor the optimization design of flow guild mold.
