摘　　要：以超深井多绳缠绕式矿井提升机试验台为研究对象,考虑风阻的影响建立了提升过程中容器的振动和钢丝绳张力的微分方程。并利用MATLAB-Simulink软件对试验台提升过程中的钢丝绳纵向振动特性进行了仿真分析,得到了在最大速度一定的情况下,提升系统以不同加速度提升运行时,钢丝绳的绳端变形、绳端变形速度、天轮处钢丝绳张力以及张力变化速度的变化规律,对提升过程加速度的输入设计有一定的指导意义。Taking the ultra deep multi-rope winding mine hoist test platform as the research object, considering the influence of wind drag, the differential equations of vessel vibration and wire rope tension in the lifting process were established. The longitudinal vibration characteristics of the steel wire ropes in the lifting process of the test bench were simulated by MATLAB-Simulink software. The variation rules of wire end deformation, wire end deformation velocity, wire rope tension and tension variation velocity at the crown wheel are obtained when the lifting system is lifted with different accelerations under the condition of a certain maximum velocity, which has a certain guiding significance for the input design of the acceleration in the lifting process.
