摘要：

采用Deform-3D有限元数值模拟软件对轮毂法兰盘热锻成形进行数值模拟，并对初定成形工艺方案进行分析，确定了预锻+终锻成形方案。针对工件表面应力较大、模具磨损较为严重的问题，通过田口试验优化法对成形参数进行优化组合。模拟结果表明，当轮毂法兰变形温度为1200 ℃、模具温度为230 ℃、变形速率为1.0 mm·s-1、摩擦系数为0.05时，工件应力、模具载荷和模具磨损能有效降低，且工件成形质量较优。各参数对零件质量和模具磨损的影响程度依次为：摩擦系数＞变形速率＞变形温度＞模具温度。

The hot forging forming process of hub flange was simulated by finite analysis software Deform-3D, and the initial scheme of forming process was analyzed to determine the preforging and to finish forging scheme. However, for the problems of greater stress on surface of workpiece and the serious wear of final mould, the parameters in hot forging were optimized by Taguchi optimization design method. The results show that the stress of workpiece, mould wear and forming load are decreased and the forming quality of workpiece is superior when the deformation temperature is 1200 ℃, the mould temperature is 230 ℃, the deformation rate is 1.0 mm·s-1 and the frictional coefficient is 0.05. Thus, the influence sequence of each parameter on the quality of part and mould wear from strong to weak is the frictional coefficient, deformation rate, deformation temperature and mould temperature.
