摘　　要：超深矿井提升多层缠绕卷筒的绳槽型式对于提升钢丝绳振动和平稳缠绕具有极其重要的影响,对多层缠绕卷筒的平行折线绳槽过渡区在不同非对称参数情况下的提升钢丝绳振动进行研究,提出研究提升钢丝绳悬绳横向振动并把其振动幅值大小作为多层缠绕绳槽非对称型式优劣的评价指标。在研究矿井提升系统及钢丝绳在过渡区运动行为的基础上,建立提升系统的动力学偏微分方程组和激励函数,应用Galerkin方法将偏微分方程组离散成常微分方程组,并以某超深矿井为例,仿真研究平行折线绳槽在两折线过渡区具有不同非对称系数情况下对提升系统振动的变化规律。研究结果表明,绳槽形式的确定,究竟选择对称布置还是非对称布置,需根据提升系统参数决定,所用研究方法和所得结果可为正确设计和选择多层缠绕卷筒的平行折线绳槽提供科学指导。The forms of grooves on a drum for ultra-deep mine hoist have extremely important effects on vibration of hoisting wire rope and smooth winding. Here,the effects of transition zone between parallel broken line grooves of a multilayer winding drum on vibration of hoisting wire rope under different asymmetric parameters were studied. The suspension rope’s lateral vibration of of hoisting wire rope was studied and its amplitude was taken as the evaluation index for asymmetric forms of multi-layer winding grooves. On the basis of studying the movement behavior in the transition zone of a mine hoisting system and wire rope,the dynamic partial differential equations of the hoisting system and the excitation function were established,and they were discretized into ordinary differential equations with Galerkin method. Taking a certain ultra-deep mine as an example,the effects of transition zone between parallel broken line grooves on vibration of the hoisting system under different asymmetric parameters were studied with numerical simulation. The results showed that either symmetric groove form or asymmetric one depends on the hoisting system’s parameters. The study method and the study results provided a scientific guidance for correctly designing and selecting parallel broken line grooves on a multilayer winding drum.
