摘　　要：汽车变速箱直齿轮要求较高的齿轮精度和力学性能。本文采用有限元软件ANSYS仿真了冷精锻过程中锻件的温度分布、应力分布以及流速分布,并对比了固定式凹模和浮动式凹模的模具载荷。结果表明,浮动式凹模有利于降低模具载荷。The spur gears of automobile gearbox require higher accuracy and mechanical properties.The temperature distribution, stress distribution and velocity distribution of the forging in the cold forging process were simulated by the finite element software ANSYS.The die loads of fixed die and floating die were compared.The results show that the floating die can reduce the die load.
