【摘要】 建立了基于研究电梯滑动导向系统横向振动特性的轿厢-导靴-导轨动力学耦合模型。该模型考虑了包括导靴与导轨的安装间隙和摩擦耦合等非线性因素,以及电梯的运行速度和负载不平衡等各种影响系统横向振动的相关因素。应用Matlab/Simulink建立该模型的仿真程序。仿真结果与实测结果在频域上的比较表明了该模型的有效性。本研究成果对于滑动导向系统优化设计、安装以及振动噪声分析和控制具有指导作用。更多还原

【Abstract】 To study the dynamic characteriticss of slide guide system in an elevator,an elevator cabin-slide guide-rail coupled lateral vibration model is developed.The mass of slide guide,the nonlinear factors such as the gap and friction between slide guide and rail,as well as the load condition(balanced or unbalanced) are all included in this model.The comparison of the simulation results through Matlab/Simulink with the experimental results illustrates the effectiveness of this model.The exploration provides an important theoretical foundation for the optimal design of a slide guide and the determination of the gap between guide and rail in assembling.In the mean time,it can be helpful for prediction and control of elevator vibration and noise.更多还原
