Analysis and Research on Contact Friction between Steel Wire Rope and Saddle of Multi-Grade Freight Ropeway

为研究多档货运索道在移动荷载作用下承载钢丝绳在鞍座上产生滑移现象，开展承载钢丝绳与鞍座滑移摩擦问题的研究，分析了承载索与鞍座间的接触作用特点，对影响摩擦系数的因素进行了总结，提出适用于承载索与鞍座的摩擦系数。建立了承载索与鞍座的有限元模型，提出了计算方案。通过仿真计算可知摩擦应力在钢丝绳同鞍座的接触中心处最大，沿着中心线对称两侧逐渐减小。并将获得的摩擦力仿真结果与试验数值进行比较，验证了仿真计算的准确性。
In order to study the sliding phenomenon of the steel wire rope on the saddle under the moving load of the multi freight ropeway, the sliding friction between the bearing wire rope and saddle and the contact characteristics between the bearing cable and saddle are studied; the factors affecting the friction coefficient are analyzed. The friction coefficient suitable for the bearing cable and saddle is put forward. The finite element model of the bearing cable and saddle is established and the calculation scheme is put forward. The results show that the friction stress is the largest at the contact center between the steel wire rope and saddle, and decreases gradually along the symmetrical sides of the centerline. The results of friction simulation are compared with the experimental results, and the accuracy of the simulation is verified.
