电梯机械系统动态特性的建模分析

Modeling for Dynamic Analysis of Elevator Mechanical System

本文对一台额定速度为 ２．５ｍ ／ｓ 的电梯进行了动态分析，通过运动弹性动力学方法建立了电梯垂直方向的振动模型。根据电梯的行程长度确定相应的运行曲线，来计算轿厢的瞬时位移，从而对模型进行了精确求解。获得了垂直方向振动加速度与加加速度的动态响应指标，为电梯机械系统动态性能的优化设计提供了依据。

By analyzing an elevator of rated speed 2.5 m/s, this article established the vibration model in vertical direction by Kineto Elastodynamic analysis method.In order to accurately solve the equation,we calculate the instantaneous displacement of the elevator according to the corresponding electrical timing curve.The article obtained the dynamic response characters and laid foundation for further optimal desing of the elevator mechanical system.
