摘　　要：铝合金轮毂形状复杂、强度刚度要求高。本文分析了6061铝合金轮毂温锻成形工艺。运用模拟软件Forge建立了铝合金轮毂预锻、终锻成形有限元仿真模型,分析了预锻、终锻成形工艺过程中的温度、等效应力分布。结果表明:铝合金轮毂在预锻、终锻成形过程中,整体温度偏差较小;不同成形阶段和不同成形部位,轮毂等效应力值不同;轮毂结构及温锻成形工艺参数对铝合金轮毂温锻件影响较大。The shape of aluminum alloy wheel hub is complex and the strength and stiffness requirements are high. The warm forging process of 6061 aluminum alloy wheel hub was analyzed. The finite element simulation model of the pre-forging and final forging of the aluminum alloy hub was established by using the simulation software Forge. The temperature and equivalent stress distribution in the process of pre-forging and final forging were analyzed. The results show that the overall temperature deviation of the aluminum alloy hub is small in the process of pre-forging and final forging. The equivalent stress of the wheel hub is different in different forming stages and different forming parts. The hub structure and warm forging process parameters have great influence on the warm forging parts of the aluminum alloy hub.
