摘　　要：利用Deform有限元分析软件模拟了涡旋盘在无背压和背压条件下的变形特点,并应用正交试验法分析了涡旋盘背压成形过程中背压力、坯料始端温度、摩擦系数和挤压速度等工艺参数对成形过程中最大载荷及涡旋盘涡旋部分平整度的影响,以优化工艺参数,模拟出最优的成形工件,为实际生产提供有效参考。In the absence of back pressure and pressure condition,the deformation characteristics of turbine disk were simulated by deform finite element analysis software.The effects of process parameters in the forming of back pressure,such as back pressure,beginning terminal of billet temperature,friction coefficient and extrusion speed on the maximum load and the flatness of turbine were analyzed by orthogonal tests.The process parameters were optimized in order to obtain the optimal shape work piece,which can provide references for actual production.
