摘要
对曳引比为2:1的电梯进行动力学建模,将时变系统划分成有限个时不变系统对电梯模型进行动力学分析,获得了电梯在空载上行工况下的电梯振动响应,得到了在起、制动阶段电梯的加速度变化比较大的结论,为电梯动态特性的优化提供了依据。
This article establishes the dynamics model of elevator whose ratio of draft load is 2:1.It carries on the dynamics analysis by dividing the time varying elevator system into the limited time invariant system, and obtains the vibration response of the elevator under the unload and upward of work condition. The analysis gets the conclusion that the change of acceleration and the vibration of elevator cabin are bigger in the stage of start-up and brake. The conclusion provides the basis for the elc:vator dynamic characteristic optimization.
