Abstract

Abstract: The longitudinal rope dynamics in a friction hoisting system and its coupling effect with friction transmission are investigated. The tension and longitudinal vibration characteristics of the rope are obtained through experiments. The dynamics of rope and friction transmission are obtained by a validated simulation model. The results show that the rope tension is divided into the dynamic tension regime and inertial tension regime due to the multi-frequency cross-linking. The longitudinal rope vibration is embodied as random perturbation. The reduction of the friction coefficient will increase the sliding between the rope and lining, and it will be beneficial to narrowing the dynamic tension regime. The increase in the longitudinal rope vibration will reduce the friction force between the rope and lining. Highlights: The concepts of dynamic tension regime and inertial tension regime of the rope are put forward. Time frequency analysis shows that the dynamic tension regime is generated due to multi-frequency cross-linking. Coupling effect of longitudinal rope dynamics and friction pair characteristics are investigated. Dangerous skid between the rope and pulley occurs when the friction coefficient is reduced to 0.25.
