摘要
电梯属于封闭的运送设备。在大多数情况下,电梯被用于客运,所以从乘客的角度来看,电梯的设计,型式和生产都至关重要。选择适当的零部件和正确的电梯配置不仅能够保障电梯正常平稳地运行,还能够延长整套电梯设备的使用寿命。本文提出了以微分方程式定义的电梯运行的物理模型。我们以数学方式分析轿厢的固有振动和在给定的初始情况下的轿厢振动,并且记录了振动类型的相位曲线和时问曲线。
Electric elevators (lifts) belong to a group of close transportation devices. Since in most cases they are used for people transportation, designing, modeling and manufacturing that equipment is a very important issue from a passenger's point of view, The right elevator configuration with an appropriate selection of components provides not only proper and comfortable use but also lengthens life of the entire equipment.This paper pre^ents a physict^l model of a traveling elevator defined by differential equations. With a numerical method we analysed proper car vibration and proper vibration with given initial condition. We drew phase trajectories, time runs describing type of vibrations.
