摘要

为确保机械传动设备安全运行，精准预测齿轮疲劳寿命十分必要。改进基于累计损伤理论以韧性为变量的多级载荷下损伤预测模型，通过两级载荷作用下弯曲疲劳试验结果，根据两级应力幅值之比与弯曲疲劳损伤间的关系拟合损伤缩放因子，将损伤缩放因子用于改进原有模型。改进后的弯曲疲劳寿命预测模型可以较为精准的预测齿轮弯曲疲劳寿命。通过与多种加载顺序下弯曲疲劳试验结果对比，预测结果与试验寿命均值偏差率较小。

Abstract

To ensure the safe operation of mechanical transmission equipment, it is necessary to predict gears′ fatigue life accurately. Based on the cumulative damage theory and the flexural fatigue test results under two-stage loads, the relationship between the ratio of two-stage stress amplitudes and the bending fatigue damage is established in this paper. The relationship is used to improve the original model. The improved bending fatigue life prediction model can accurately predict the bending fatigue life of gears. Compared with the bending fatigue test results under multi-stage loading under various modes, the prediction result has a small deviation from the average test life.
