摘　　要：运用Deform-3D软件,对曲轴预锻成形过程进行了数值模拟,得到了模具表面及筋板表层的温度场。同时以500℃作为等效回火温度,分析了材料在不同回火时间下的硬度、显微组织变化。最后测量了失效模具筋板部位的硬度变化,为热锻模具硬度的进一步研究提供参考。Pre-forging process of crankshaft was simulated by deform-3D software, the temperature field of die＇s surface and plate was achieved. The variation of hardness and microstructure on different tempering time was analyzed using 500 ℃ as equivalent tempering temperature. Then hardness variation of failure die＇s plate was measured. It provides referrence for further study on hot forging die＇s hardness.
