本文假定轮齿为半无限体,裂纹(或缺陷)为椭圆形,位于齿面或齿表层下。然后用断裂力学方法汁算其轮齿弯曲疲劳寿命(N值)。
This paper assumes that the gear tooth is a semi-infinite body, and the crack (or defect) is oval and located under the tooth surface or tooth surface. Then calculate the bending fatigue life (N value) of tooth with fracture mechanics method.
