摘　　要：根据乘客曳引电梯补偿链的实际运动形式,建立运动状态下的电梯补偿链微分方程,通过差分方法对电梯补偿链动态特性进行了数值求解,根据结果对顶层、中间层和底层的补偿链的动态悬垂曲线进行了分析,发现加速状态的补偿链与静态相比会发生向轿厢或对重侧偏移。该结果对电梯井道部件的设计具有重要指导意义。According to the actual motion form of the passenger traction elevator compensation chain,the differential equation of the elevator compensation chain under the motion state is established,and the dynamic characteristics of the elevator compensation chain are numerically solved by the difference method.According to the results,the dynamic sag curves of the compensation chain of the top,middle and bottom layers are analyzed.It is found that the compensation chain in the acceleration state will shift to the car or the counterweight compared with the static state.This result has important guiding significance for the design of elevator shaft components.
