摘要

The fretting fatigue properties of pearlitic and bainitic steel with medium carbon steel contactmaterial were examined using the clamping contact double bridge pads system. In order to investigatethe effects of contact pressure and relative slip amplitude on fretting fatigue strength, the frettingfatigue tests were carried out under the conditions of two contact pressures and three pad lengths.The fretting fatigue strength decreased with increasing contact pressure and with increasing padlength at the constant contact pressure of 98MPa. Also crack initiating position moved from the edgeto the center of fretted damage surface with decreasing contact pressure. Interrupted fretting fatiguetests were carried out in order to investigate the fretting damage and the crack initiation at the padlength of 30mm and the contact pressures of 49, 98 and 196MPa. The saturation of fretting damageoccurred beyond a certain number of fretting cycles, and the ratio of number of cycles to saturation offretting damage was about 50 to 60% in the present conditions. And the ratio of number of cycles tocrack initiation was less than 20% in this study.
