The transverse vibration of a wire rope and the effect on friction transmission stability in a friction hoisting system are investigated. A simulation model is established by Adams/cable and then it is validated by an experimental device using the time-frequency technology. The influence of different factors (including speed, acceleration, load, rope length) on transverse vibration is discussed. A method is employed to weaken the transverse vibration by adjusting the initial acceleration time. The results show that, the transverse vibration reduces the actual contact area of the wrap angle. The intensification of transverse displacement at the tangent point of the pulley reduces the friction force of the following rope in the wrap angle and increases the instability of the friction force. •A simulation model and experimental device of the friction hoisting system are established.•Time-frequency technology is employed to analyze the transverse rope vibration.•Friction characteristics between the rope and pulley are obtained at any time and any position.•Correlation between transverse rope vibration and friction stability between the rope and pulley is established.
