Research on the Dynamic Characteristics of High-Speed Elevator System

The present paper studied on the high-speed traction elevator developed by Dongnan Elevator Co., Ltd. And the seven degrees of freedom differential equations of a highspeed traction elevator are established by the Lagrange approach. The natural frequencies of the elevator system are carried out through model analysis. The harmonic analysis of high-speed traction elevator is carried out to obtain the vibration characteristic of elevator car and determine the considerable impact model frequencies on the dynamic performance of elevator car. The influences of elevator car load, rubber stiffness under elevator car and rubber stiffness under tractor on the vibration characteristics of elevator car are investigated in detail. The conclusions of this paper provide theory basis for the elevator’s dynamic design, troubleshooting and structure optimization.
