电梯的抗震计算分析

The Calculation and Analysis of Earthquake Resistance of Elevator

本文在现有的电梯系统动力分析理论的基础上 ,进一步分析电梯系统的振动。文中建立起电梯系统垂直和水平方向的振动模型 ,然后把建筑物的地震响应作为激励输入模型。列出系统的运动微分方程组 ,并解出系统主要部件的动力响应时间历程 。

Based on the present theory of dynamic analysis of elevator system, the vibration of elevator is further analyzed in this paper. Vibration models of the elevator system in the horizontal and vertical direction are established respectively. The seismic responses of the building are used as excitation and imput into the model. Differential equations of the system are set up and the time history of the dynamic responses of the main parts are worked out. And then some earthquake protective measures for elevators are proposed.
