摘    要:基于Archard磨损模型与Abaqus自适应网格技术建立了仿真分析过盈配合结构微动磨损的计算模型,对配合面轮廓随循环周次的变化进行了预测,并详细研究了微动磨损对接触压应力、摩擦剪切应力及微动滑移幅值等微动参量的影响.结果表明:该计算模型能够较为准确地对配合面轮廓随循环周次的变化进行预测;由于微动磨损的作用,配合边缘处接触压应力的峰值逐渐增大,且其位置逐渐向配合内部移动;摩擦剪切应力的最大值逐渐由黏着-滑移过渡位置向磨损-未磨损过渡位置移动;张开区域的宽度以及滑移区内各位置处的微动滑移幅值均随着循环周次的增加而增大.

关 键 词:微动磨损  过盈配合  Archard磨损模型  自适应网格技术

Abstract:The numerical simulation method was developed based on the Archard method and the Arbitrary Lagrangian-Eulerian adaptive meshing (ALE adaptive meshing) within the Abaqus. The evolution of the surface profile with fretting cycles was predicted based on the numerical method, and the influences of fretting wear on the contact pressure, the frictional shear stress and the slip amplitude were investigated in detail. The results show that the evolution of the surface profile can be predicted accurately by the numerical method. It is found that the peak value of contact pressure at the contact rim increases and the location of it moves inward towards the contact zone gradually due to the fretting wear. The location of the maximum frictional shear stress shifts from the stick-slip boundary to the worn-unworn boundary. Meanwhile, the width of open regime and the slip amplitude on the slip regime increase with increasing cycles.
Keywords:fretting wear  press-fitted  Archard method  ALE adaptive meshing
