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K_(TZ)、垂向转动阻尼系数C_(TZ)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。
Aiming at the short life span of the tail rope caused by the swaying of the tail rope during the ascending movement of the deep shaft hoist, the viscoelastic vibration model of the tail rope was established by using the discrete dynamic modeling (ADAMS) , To achieve the simulation of the tail rope movement, study the swing characteristics of the tail rope. The design test records the tail rope swing at the bottom of the wellbore and compares with the simulation results to verify the rationality of the model. Analysis of different parameters on the impact of the tail rope swing. The results show that the tail rope micro-section has the maximum swing displacement on the left and right sides at the bottom of the wellbore. The tail rope swing is closely related to the vertical rotation stiffness coefficient K_ (TZ) and the vertical rotation damping coefficient C_ (TZ) , The left and right swings were the most affected by the vertical rotation damping coefficient and mass, respectively, increased by 26.41% and 21.75% respectively after individually increasing 50% of their own parameters. Experimental results and simulation results are basically the same, can be tail rope selection, construction of isolation devices provide a reference.
