基于VPT高速电梯性能分析及动力学参数优化

高速电梯在水平和垂直方向的振动是影响舒适感的主要因素。为了提高舒适型并缓解振动和冲击对电梯内部仪器的影响，对电梯振动的动力学参数进行了优化。通过虚拟样机技术(virtual prototype technology，简称VPT)在虚拟样机中完成对高速电梯运行过程中速度和加速度的仿真分析；运用灵敏度分析法，分别通过固有频率分析和信号频域分析对影响电梯系统垂直和水平方向的振动动力学参数进行了优化。仿真结果显示，优化后的电梯系统垂直方向的振动加速度由原来的1.12 m/s2降为1.04 m/s2，轿厢水平方向的振动加速度小于0.1 m/s2，使垂直和水平方向的振动加速度最大幅减小，提高了电梯的乘坐舒适感，为高速电梯系统的优化设计与研发提供一条有效途径。

Dynamic Performance Analysis and Kinetic Parameters Optimization of High-Speed Elevator Based on VPT

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 1.12 m/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.
