Influence of High-speed Elevator Operation Parameters on Longitudinal Vibration of Time-varying Hoisting System

摘要

Based on the finite deformation theory and Hamliton principle, considering the time-varying characteristics of the steel wire rope, the longitudinal vibration time - varying model of high - speed elevator hoisting system is established, and the longitudinal vibration dynamic equation of hoisting system is obtained. Though the precise integration method, the motion state curve and elevator car's longitudinal vibration acceleration curve of the high-speed elevator under different operating parameters are obtained. The results show that within a certain range, the upstream acceleration has a significant effect on the longitudinal vibration of the hoisting system; With the increase of the upstream acceleration, the longitudinal vibration displacement of the elevator car increases obviously; With the increase of the upstream acceleration, the acceleration of the longitudinal vibration of the car is firstly obviously increased and then Increasing trend tends to be slow.
