摘　　要：在完成42CrMo材料硬齿面齿轮大样本全寿命成组试验的基础上,通过试验数据处理获得了定寿命下极限应力概率分布和R S N曲线。提出有限元疲劳寿命预测法的研究策略和实施方法,采用虚拟技术得到了42CrMo齿轮应力寿命曲线,与实际试验齿轮S N曲线较为接近。Based on the big samples and full life tests for 42CrMo-hardened gears, fatigue limit stress under certain life and R-S-N curves were evaluated by processing method of testing data. Research strategy and testing method on estimating fatigue life by finite element method were presented. Stress-cycle curve of 42CrMo gear that is close to practical S-N results were gained.
