| 中文摘要: |
| 对直齿轮温锻成形过程进行数值模拟，选取不同参数和水平进行正交试验设计，将齿轮的成形力和凹模模具磨损作为两项指标，并基于该两项指标分析试验结果，得出坯料初始温度、模具预热温度、工模间摩擦系数、锻压速度对成形过程的影响，并获得较优的工艺参数值。模拟结果与实验结果吻合，对实际生产起到了指导作用。 |
| 英文摘要: |
| The process of spur gear warm forging was simulated with different factors and different levels being chosen in the orthogonal experiment．Based on the forming force and the value of die wear, rationalized technological parameters were obtained including initial temperature of blank, preheat temperature of die, the friction coefficient and pushing speed．So that certain theory guidance was provided to draft the process of warm forging and to improve the die life. The simulation is in agreement with experimental results. It has provided a theoretical basis to guide the practical production. |
