| 目的 研究不同加载相位差下微动磨损量随切向载荷幅值的变化规律。方法 在ABAQUS中建立柱面/平面微动磨损模型，设置不同的加载相位差，结合能量模型和UMESHMOTION子程序，进行仿真试验，对不同情况下的磨损深度进行仿真分析。结果 法向载荷、位移载荷和应变载荷取定值时，0°相位差的磨损深度最小，180°相位差的磨损深度最大，90°和270°相位差的磨损深度相同，且介于二者之间；当法向载荷和位移载荷为定值时，0°相位差的磨损深度随应变载荷的增大而减小，90°相位差的磨损深度不受应变载荷幅值的影响，180°相位差的磨损深度随应变载荷的增大而增加，且接触状态由部分滑移向完全滑移逐渐过渡；当法向载荷和应变载荷一定时，随位移载荷的增加，各相位差下磨损宽度和磨损深度都呈现出增大的趋势；在部分滑移状态下，当应变载荷较大时，0°相位差的最大磨损深度发生在接触区后缘，180°相位差的最大磨损深度发生在接触区前缘，90°相位差的前、后缘磨损深度极大值接近。结论 两切向载荷间加载相位差对磨损深度随切向载荷幅值变化的趋势影响明显，0°相位差的磨损深度最小，相位差对最大磨损深度的产生位置也有影响。 |

| 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. |
