摘要

绳索引导式输送机的横向振荡行为非常复杂，因此绳索引导式提升系统至今仍未得到透彻的理解。本研究利用 CFD 工具，通过编写用户自定义函数（UDF）获得了作用在输送机上的空气动力，然后利用 Matlab 对导绳输送机的振荡行为进行了数值研究，并考虑了导套和导绳之间的间隙变化。通过考虑导套和导绳之间的间隙，建立了绳索引导输送机的非平稳振荡模型。结果表明，在运输工具相互通过时，空气动力缓冲力对绳索引导运输工具的振荡行为有显著影响。随着间隙的增大，绳索引导输送机的横向加速度变化不大。然而，输送机的振荡幅度与绳索导向套筒间隙呈正相关。

The Influence of Rope Guide Sleeve Clearance on the Lateral Oscillation of Rope Guided Conveyance in Mine Hoist System caused by the Aerodynamic Force

The lateral oscillation behaviour of rope guided conveyances was so complicated that the rope guided hoisting system hasn’t been understood thoroughly so far. In this study, the CFD tool was used to obtain the aerodynamic force acting on the conveyance by writing a user-defined function (UDF), and then the oscillation behaviour of rope guided conveyances was investigated numerically by Matlab with the variation clearance between the guide sleeve and the guide rope. A non-smooth oscillation model of the rope guided conveyance was established by considering the clearance between the guide sleeve and the guide rope. Results show that the aerodynamic buffeting forces had a notable influence on the oscillation behaviour of rope guided conveyances during the conveyances passing each other. The lateral acceleration of the rope guided conveyances showed a minor change with the increase of the clearance. However, the oscillation amplitude of the conveyances manifested a positive correlation with the rope guide sleeve clearance.
