| 摘 要： | 基于修正的Archard理论,采用弹塑性有限元模型对螺旋锥齿轮热锻成形的模具磨损进行了模拟仿真，分别从齿模齿顶的过渡圆弧半径、模具热处理硬度、模具的预热温度以及锻造成形速度四个方面对模具易磨损位置的磨损量进行计算,采用正交试验优化设计方法分析各工艺因素对模具寿命的影响规律,确定最优的工艺参数进行锻造试验。试验结果表明,使用提出的预测模具寿命的方法估算的模具寿命与试验结论具有较好的一致性。

| Abstract: | The die wear was simulated by elasto-plastic finite element model herein.Based on the modified Archard method,the die wear was analyzed from four processing factors,which were the addendum transition arc of tooth die,the die hardness,initial die temperatures and the forming velocity.Through the simulation results,die service life influenced by the processing factors was revealed.The optimal processing factor combination guiding the experiment was proposed by orthogonal experimental design.The experimental results indicate that there is
expected consistency between the die service life and the experimental conclusion by using the method preceded herein. |

| Keywords: | spiral bevel gear die service life die wear orthogonal experimental design |
