Abstract Fretting wear has a significant influence on wire rope fatigue life when in cyclic bending, particularly for crossed wire contacts, where the interfacial motion of the surfaces is complex and multi-axial. To simulate these contacts in a controlled manner, a laboratory-scale, crossed cylinder, reciprocating fretting wear test was developed. A broad range of contemporary lubrication technologies were evaluated using this method, and a systematic multivariate statistical analysis was performed to identify the most significant lubrication-related parameters with respect to these fretting wear conditions. Wear area increase per slip cycle was the most relevant measure of wear damage, because this captured the influence of changes in the fretting wear regime during the test. The ability of a lubricant to reduce damaging fretting wear during the running-in phase was the greatest influence on long-term fretting wear, particularly for grease-lubricated contacts.

钢丝绳微动接触的代表性摩擦计测试:润滑对微动磨损的影响

摘要 循环弯曲时,微动磨损对钢丝绳的疲劳寿命有显着影响,特别是对于交叉线接触,其表面的界面运动是复杂的和多轴的。为了以受控方式模拟这些接触,开发了实验室规模的交叉圆柱往复微动磨损测试。使用这种方法评估了广泛的当代润滑技术,并进行了系统的多变量统计分析,以确定与这些微动磨损条件相关的最重要的润滑相关参数。每个滑移循环的磨损面积增加是磨损损坏的最相关度量,因为这捕获了测试期间微动磨损状态变化的影响。
