The work aims to study the variation of fretting wear parameters with tangential load amplitude under different loading phase differences. A dynamic cylinder/flat wear model was established in ABAQUS and different loading phase differences were set up to conduct the simulation test based on the energy model and the UMESHMOTION subroutine to analyze the wear depth of different loading conditions. When normal load, displacement load and strain load were constant value, the wear depth of 0° phase difference was the smallest, the wear depth of the 180° phase difference was the largest and the wear depth of 90° phase difference was the same as that of 270° in the middle. When the normal load and displacement load were fixed, the wear depth of 0° phase difference decreased with the increase of strain load and the wear depth of 90° phase difference was not affected by the strain load amplitude, but the phase difference of 180° increased as the strain load increased and the contact state gradually transferred from partial slip to full slip. The wear width and the wear depth at different phase differences increased with the increase of the displacement load when the normal load and the strain load were constant. In addition, the phase difference of 0° had the largest wear depth at the trailing edge of the contact zone, while the largest wear depth of 180° phase difference occurred at the leading edge of in the partial slip state. However, the maximum wear depth of 90° phase difference in the trailing edge and leading edge of the contact zone was equivalent. The phase difference of two tangential loads had a significant influence on the wear depth with the variation of tangential load amplitude, and the wear depth of 0° phase difference is the smallest. The phase difference also affects the position of the maximum wear depth.
