摘　　要：用Deform软件对6082铝合金汽车后上控制臂楔横轧轴坯成形工艺进行数值模拟,研究坯料加热温度、模具温度对楔横轧轴坯温度场、损伤系数、点应力等的影响,并进行试验验证。结果表明:坯料预热温度T_(b)、模具预热温度T_(m)升高均会促进轧件内部高温区的形成,当T_(b)=450℃,T_(m)=100℃时,轧件内部温度场分布合理,且坯料表面、内部损伤系数分别小于0.626、0.375,应力曲线变化平缓。在轧制角速度为1 rad/s,T_(b)=450℃,T_(m)=100℃时,6082铝合金汽车后上控制臂楔横轧轴坯成形良好。Deform software was used to numerically simulate the forming process of the 6082-aluminum alloy automobile rear upper control arm with cross wedge rolling.The influence of the preheating temperature of billet and die temperature on the temperature field,damage coefficient,point stress,etc,were theoretically analyzed and experimentally verified.The results show that the increase of preheating temperature billet T_(b)and die preheating temperature T_(m)will promote the formation of high temperature zone inside the rolled piece,and the internal damage coefficients are less than 0.626 and 0.375,respectively,and the stress curve changes gently.The billet is well formed and in perfect agreement with the numerical simulation results under the conditions of rolling angular velocity of 1 rad/s,T_(b)=450℃and T_(m)=100℃.
