摘　　要：给出了矿井提升系统振动微分方程和S形曲线算法,并分别在折形速度给定和S形给定下,对提升过程进行仿真,最后对两种仿真结果进行定量比较分析。研究表明,S形速度给定可以大大减小提升中的系统冲击,改善钢丝绳受力情况,提高提升的平稳性,同时还可为提升钢丝绳的选用和提升机运行控制方式的设计与改进提供参考。In this paper, the vibration differential equation and S--shaped curve algorithm for the mine shaft hoist system are presented. The paper simulates the hoisting conditions with and without S--shaped curves, analyses and compares the results quantitatively. Study indicates that impacts on hoisting system decrease and steel wire rope tension reduces with S--shaped curve and the hoisting could become smoother and steadier. This paper also provides references to wire rope selection, design and innovations of hoist travel control.
