采用有限变形弹塑性有限元方法 ,以型材挤压过程的有限元模拟为基础 ,研究了局部挤压比、挤压带面积和模孔距离对金属流动速度的影响 ,获得了型材挤压过程的一般变形规律。
Based on the finite element simulation of the profile extrusion process, the effects of the partial extrusion ratio, the area of the extrusion zone and the distance between the die holes on the flow rate of the metal were investigated by using finite deformation elasto-plastic finite element method. The extrusion process of the profile was obtained General deformation rules.
