沟槽对界面振动及摩擦磨损特性的影响

Effect of Groove on Interface Vibration and Friction and Wear Behaviors

  • 摘要: 选用球-面/面-面两种不同的接触模式,分别探究了摩擦界面沟槽的存在对界面振动及摩擦磨损特性的影响. 结果表明:沟槽具有捕获磨屑的能力,能够有效地减轻磨屑对界面磨损的影响,但接触模式的不同,沟槽棱边上的振动及摩擦磨损特性差异显著. 在球-面接触模式下,沟槽的存在打断了界面的连续接触,导致界面摩擦信号产生突变,此外,球试样滑过沟槽时与沟槽棱边产生的撞击加剧了棱边的磨损,进而影响了沟槽收集磨屑的效率. 在面-面接触中,沟槽的存在实时改变了界面的接触状态,从而导致了界面上接触压力的分布发生了转移,从而改变了界面力信号,此外,块试样与沟槽棱边并没有出现明显的撞击作用,因此沟槽的棱边保存得较为完好.

     

    Abstract: In this work, the effect of groove on vibration and friction and wear properties was performed in ball-on-flat and flat-on-flat contact configurations. The results show that the groove had a capacity in trapping wear debris from the contact surface, which consequently alleviated the effect of wear debris on interfacial wear effectively. In addition, it is found the groove edge showed significant different vibration and tribological properties in the two contact configurations. In the ball-on-flat configuration, the groove interrupted the continue contact of the contact interfaces, which accordingly caused the abrupt change of the friction signals. Moreover, the collision behavior generated between the ball and groove edge further exacerbated the wear of the groove edge, and consequently affected the efficiency of groove in trapping wear debris. In the flat-on-flat configuration, the variation and redistribution of contact pressure was the major reason for the change of interfacial force signals, and no visible collision behavior was found between the pad and the edge of groove.
