Effect of various kinematic parameters of mine hoist on fretting parameters of hoisting rope and a new fretting fatigue test apparatus of steel wires

The effect of various kinematic parameters of mine hoist on fretting parameters of the hoisting rope was investigated and a new fretting fatigue test apparatus was designed. A simulation model of the rope tension was presented to examine the role of various kinematic parameters on the rope tension and tension amplitude during lifting. Ranges of fretting parameters of the rope during lifting with different kinematic parameters were determined. The results show that different kinematic parameters induce different modal shapes of the vibrating systems during lifting, which results in distinct ranges of fretting parameters of the rope.

► We build simulation models of the tension and fretting parameters of hoisting rope.
► Different kinematics parameters induce distinct modal shapes of the hoisting systems.
► Kinematics parameters of mine hoist affect the fretting parameters of hoisting rope.
► We design a new fretting fatigue test apparatus of steel wires.
