Based on continuum mechanics theory and considering the influence of external excitation on high-speed traction elevator wire rope, Hamlition principle is applied to establish the transverse vibration control equation of variable-length lifting wire rope, and Galerkin method is used to discretize the solution. Finally, the model is simulated by Matlab software, and the transverse vibration law of the wire rope and the influence of damping on the transverse vibration of the wire rope are analyzed. The results show that the transverse vibration strength of the wire rope is basically the same as that of the wire rope when there is no damp effect. Increasing the damp can reduce the transverse vibration strength of the wire rope.
