摘要
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。
The vibration is the main force affecting elevator comfort. In order to study the dynamic characteristics of the 4.0 m/s ultra-high-speed elevator system, the lift cabin-car frame-guide rail-wire rope coupled system was taken as the study object. First, the vibration dynamic model of vertical system was built. Then, combined with automatic dynamic analysis of mechanical systems virtual prototyping technology, the elevator virtual prototype model was built by establishing rope？s dynamics model, adding a contact force between the guide rail and the guide shoe, adding horizontal vibration excitation and vertical vibration excitation. Dynamic characteristic simulation was carried out for this model under setting certain constraints and drivers. The results showed that those performance indicators such as vertical vibration acceleration and horizontal vibration acceleration were meeting the requirements and the simulation results also provided design basis for the development of ultra-high-speed elevators.
