本文在讨论齿轮弯曲载荷谱的基础上,借助疲劳寿命和疲劳强度之间的破坏率等同性原理,根据齿轮弯曲疲劳寿命分布求出其疲劳强度概率分布.应用实例显示了该模型能反映出齿轮弯曲疲劳强度随时间延续而变化的动态关系.
Based on the discussion of the bending load spectrum of gears, the probability distribution of fatigue strength is obtained from the bending fatigue life distribution of gears by means of the sameness principle of failure rate between fatigue life and fatigue strength.The application example shows that the model can reflect the gear The dynamic relationship between the bending fatigue strength and the time lapse.
