摘　　要：针对深井摩擦提升系统中,钢丝绳在提升过程中张力的变化情况,分析了钢丝绳在提升周期内承载状况的变化规律,建立了提升过程中钢丝绳动态张力的数学模型,并选用精度高、速度快的龙格-库塔法进行数值分析.根据所建数学模型,建立了基于Matlab/Simulink的提升钢丝绳动态张力仿真模型.通过案例仿真结果表明了钢丝绳提升周期内三个运行阶段之间张力突变现象的主要影响因素有悬垂绳长、载荷和加速度,为进一步研究上述三个因素的量化限制范围,实现多绳摩擦提升机平稳运行提供了前提依据.This paper analyzed the changing law of the steel wire rope in hoisting period. Using fast and high-precision Runge Kutta method,a mathematical model was established for the dynamic tension of the wire rope in the hoisting process. According to the mathematical model,the dynamic tension simulation model of hoisting rope based on Matlab/Simulink was established. Through the case simulation,the main factors affecting the tension sudden change phenomenon between the three operation stages of steel rope hoisting cycle were analyzed,which is the premise for the safe and smooth operation.
