摘　　要：利用MSC.Marc和MSC.SuperForge两种数值模拟软件对铝合金挤压棒材件进行分析对比,有限体积法在工程应用中对大挤压比、形状复杂的型材的挤压成形计算具有较大的优势。针对平面导流模具和分流模具对其在挤压过程中坯料的应力分布和速度场分布进行了详细的比较分析,发现坯料应力的分布与工作带高度的设定、出材的流动是否均衡没有直接的联系。Two numerical simulation software, MSC. Marc and MSC. SuperForge, are used in this paper to analyze the simple extrusion forming process of rods of aluminum ＂alloy. It is found that finite volume method has many advantages in the application of large extrusion ratio and complex profile extrusion process computation. Then, targeting at plane die and poahole die, we continue to study the stress distribution and the material flow distribution by using finite volume method and find that the stress distribution of the billet has no direct relation with the lengths of the beating and the equilibrium of the material flow.
