摘要
The effect of terminal mass on fretting and fatigue parameters of the hoisting rope during a lifting cycle in coal mine was investigated in this study. Static analyses of the rope were performed at the start and end of the lifting cycle as compared to dynamic analyses during lifting. Correlation models between rope tensions and fretting and fatigue parameters were established. The results show that overall ranges of wire tension, relative displacement and contact load between wires in the rope are 1.5–175.6 N, 0.9–99.6 μm, and 0.2–452.9 N with the terminal mass increasing from 1000 to 1700 kg. Increases of fretting and fatigue parameters shorten the rope life.
