| 英文摘要 | 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. |
