Abstract: In order to reduce high-speed elevator vibration to improve its riding comfort, the
virtual prototype model of high-speed elevator is set up by Solidworks and Adams. The dynamic
analysis and simulation of the whole running situation of the elevator are made. The effect of the
main dynamics factors to the high-speed elevator vibration received by sensitivity analysis of the
high-speed elevator vibration signal is obtained. The dynamics parameters of the elevator are
optimized by frequency domain analysis of vibration signal and natural frequency analysis for
multi-body system. The simulation result shows various dynamic characteristics have been great
improved after optimization. This simulation result provides reference for improving performance of
elevator.
