摘要： 针对深井提升机提升运动中尾绳摆动引起的尾绳寿命短的问题,采用离散化建模的方法,使用机械系统动力学仿真软件(automatic dynamic analysis of mechanical systems, ADAMS)建立尾绳黏弹性振动模型,实现尾绳的运动仿真,研究尾绳的摆动特性。设计试验记录井筒底部回转处尾绳摆幅,并与仿真结果比对,验证模型的合理性。分析不同参数对尾绳摆幅的影响。结果表明:尾绳微段在井筒底部回转处分别产生左右两侧的最大摆动位移,尾绳摆幅与垂向转动刚度系数KTZ、垂向转动阻尼系数CTZ以及质量密切相关,左右摆幅分别受垂向转动阻尼系数和质量影响最大,在单独提高50%自身参数后,分别增加26.41%和21.75%。试验结果与仿真结果基本一致,可为尾绳选型、构建隔离装置提供参考。

Abstract: To solve the short-life problem of hoist tail rope caused by the swing of tail rope during the lifting movement, the visco-elastic vibration model was built based on the discretization modeling method and the ADAMS(automatic dynamic analysis of mechanical systems) software. The characteristic of the tail rope was studied by implementing the motion simulation. The test was designed to record swing amplitude of the tail rope at the shaft bottom. Test results were compared with simulation results to verify the rationality of the model. The influence of different parameters on the swing amplitude of the tail rope was analyzed. The results showed that the maximum swing amplitude of the micro segments of tail rope was generated at the shaft bottom, which was closely related to the vertical rotational stiffness coefficient KTZ and the vertical rotation damping coefficient CTZ as well as the mass. The left swing amplitude was most greatly influenced by the rotational stiffness coefficient while the right swing amplitude was most affected by the mass. When 50% improvement of the parameters of the model is achieved, the left and right swing amplitude were increased by 26.41% and 21.75%, respectively. Test results were basically in line with the simulation results, which could provide a reference for the selection of tail rope and construction of the isolation device.

Key words: swing amplitude, discretization modeling, motion simulation, visco-elastic vibration model, tail rope
