摘要

梯度结构设计是改善齿轮钢滚动接触疲劳的一种很好的方法。采用实验和建模方法研究了梯度结构齿轮钢的滚动接触疲劳行为。在滑差为0%的油润滑条件下，对两个圆柱形接触试样进行了RCF试验。公称赫兹接触应力表示的疲劳性能是相似的。温度的升高会降低赫兹应力。这抵消了温度对材料疲劳性能退化的影响，从而表明在低温和高温下的标称疲劳性能是相似的。在接触表面下观察到裂纹和明显的塑性变形区。在I-H寿命预测模型的基础上，提出了考虑材料梯度结构的RCF寿命模型。RCF试验获得的实际疲劳寿命均在模型的失效概率预测范围内，验证了寿命预测模型的有效性。

Modeling on rolling contact fatigue life of gear steel with gradient structure

Gradient structure design is an excellent method for improving the rolling contact fatigue of gear steel. The rolling contact fatigue (RCF) behavior of gradient structure gear steel was investigated by experimental and modeling methods. RCF tests were conducted on two cylindrical contact specimens under oil lubrication conditions with a slip ratio of 0 %. The fatigue performance indicated by the nominal Hertzian contact stress is similar. The increase of the temperature will decrease the Hertzian stress. This offsets the impact of temperature on the material's fatigue performance degradation, thereby showing that the nominal fatigue properties at low and high temperatures are similar. Cracks and significant plastic deformation regions were observed beneath the contact surface. A RCF life model considering material gradient structure was proposed based on the I-H life prediction model. The actual fatigue life obtained from RCF tests fell within the failure probability prediction range of the model, validating the effectiveness of the life prediction model.

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
