摘　　要：采用复变共形映射理论 ,对异型材挤压模及金属塑性变形体进行系统建模 ,并建立塑变形体的能量方程 ,根据极值原理 。According to the complex conformal mapping principle, a systemic modeling was made on the extruding die for special-typed metals and the plastically deforming metals. The energy equation of the plastically deforming metals was set up. According to the principle of extreme values, the optimizing design parameters for special-typed metals extruding was inferred.
