The main factors that affect comfort in speed elevators are horizontal and vertical vibrations. To improve comfort and mitigate the effects of vibration and shock inside elevator equipment, the kinetic parameters of the elevator vibrations are optimized. The process of running the speed and acceleration of the high-speed elevator in the virtual prototype simulation by virtual prototype technology (VPT) technology is completed, a sensitivity analysis method is used, and the kinetic parameters of vibrations that affect the vertical and horizontal directions of the elevator system are optimized. The simulation results show that the vertical vibration acceleration of the optimized elevator system dropped from 1.12m/s2 to 1.04 m/s2, and the horizontal vibration acceleration of the lift car is less than 0.1 m/s2.This ensures that the maximum amplitude of the vertical and horizontal vibration acceleration is reduced, the ride comfort of the elevator is improved, and an effective way to optimize the research and design of the high-speed elevator system is provided.
