直齿轮径向挤压过程金属流动的上限元模拟

Numerical Simulation of the Metal Flow Behaviours during Radial Extrusion of Spur Gear

利用上限元（ＵＢＥＴ）模拟了圆柱直齿轮径向挤压过程金属的流动行为，分析了模具参数和工艺参数对金属流动的影响。

The metal flow behaviours during radial extrusion of spur gear are simulated by using UBET in this paper .The influences of die parameter and technological parameter on the metal flow during radial extrusion of spur gear are analyzed.
