| 摘 要： | 用一个新的基本观点-把齿轮弯曲疲劳失效处理成随机事件, 以这个随机事件为研究对象, 用齿轮弯曲疲劳的累积损伤强度Kw和总疲劳损伤量Dw来描述弯曲疲劳失效随机事件, 得出用概率描述的弯曲疲劳的疲劳累积损伤模型。用这个计算模型, 提出了计算齿轮弯曲疲劳可靠度的方法。

| Abstract: | A new viewpoint is taken that the fatigue failure of the gear under bending load is treated as a random event,and a method for predicting the gear fatigue strength reliability under bending load is obtained from researching the event.Two new random variables K W and D W are proposed to describe the random event of bending fatigue failure of the gear. K W is the fatigue damage strength which indicates the inherent ability of the gear to resist the fatigue damage under bending load. D W is the overall fatigue damage quantity which indicates the fatigue damage degree of the gear under bending load in the life span.A cumulative fatigue damage probabilistic model of the gear fatigue strength estimation under bending load is established by means of K W and D W .Basd on the model,a predicting method is provided for the gear bending fatigue reliability. |
