超高速电梯系统动态仿真分析

电梯的振动是影响舒适性的最主要因素，针对4.0 m/s 超高速电梯系统，以轿厢-轿架-导轨-钢丝绳耦合系统为研究对象，建立垂直系统振动动力学模型，结合机械系统动力学自动分析虚拟样机技术，通过建立钢丝绳动力学模型、添加导轨与导靴之间的接触力、水平振动激励及垂直振动激励，建立电梯整机虚拟样机模型，设定约束与驱动，进行动态特性仿真分析。仿真结果表明，电梯垂直振动加速度、水平振动加速度等性能指标满足要求，为超高速电梯的开发提供了设计依据。

Dynamic Simulation of Ultra-High-Speed Elevator System

The vibration is the main force affecting elevator comfort. In order to study the dynamiccharacteristics of the 4.0 m/s ultra-high-speed elevator system, the lift cabin-car frame-guide rail-wirerope coupled system was taken as the study object. First, the vibration dynamic model of verticalsystem was built. Then, combined with automatic dynamic analysis of mechanical systems virtualprototyping technology, the elevator virtual prototype model was built by establishing ropes dynamicsmodel, adding a contact force between the guide rail and the guide shoe, adding horizontal vibrationexcitation and vertical vibration excitation. Dynamic characteristic simulation was carried out for thismodel under setting certain constraints and drivers. The results showed that those performanceindicators such as vertical vibration acceleration and horizontal vibration acceleration were meetingthe requirements and the simulation results also provided design basis for the development ofultra-high-speed elevators.
