摘要
提升绳系的激励加速度决定着提升容器的乘坐舒适性和提升钢绳中动张力的大小 ,过大的动张力将导致滑绳 (摩擦提升 )或断绳 (缠绕式提升 )。基于提升钢绳为连续弹性杆的条件 ,建立了绳系的偏微分方程 ,采用特性线数值分析方法 ,以满足提升容器的乘坐舒适性和提升钢丝绳产生较小动张力为目标 ,对矿井提升机绳系要求的合理激励加速度曲线进行了反演分析与设计。
The prompting acceleration of hoisting rope system determines the winders' sitting comfort and the dynamic load in hoisting rope. The over dynamic load is the main factor which leads slipping or breaking out of hoisting rope. Based on the condition that the hoisting rope. Be regarded as the continuous flexible rod, and the equation of hoisting rope system, by the characteristic lines numerical value analyzing method and taking the ride comfort of hoisting cage and the little dynamic oscillation of hoisting rope as the aim, the rational acceleration curve of rope system is brought out in this paper, and it can provide reference for further study and design of mine winders.
