Abstract: The paper focuses on predicting and reducing the spatial transverse vibrations of hoisting catenaries, which may cause disordered rope arrangement, induced by drum winding in super-deep mine hoists. Firstly, the governing equations of spatial transverse vibrations of a hoisting catenary and the rope tension have been derived and experimentally validated; subsequently, the functions of the spatial transverse excitation displacements at the drum end and the hoisting velocity have been precisely modelled and calculated, numerical simulation indicated that large amplitude spatial vibrations will be excited by drum winding and that the quasi-static rope tension can be employed to predict the spatial transverse vibrations of the catenary. Eventually, a vibration isolated system is proposed to reduce the spatial transverse vibrations of a catenary, numerical simulation validated the feasibility. The paper will provide good technical supports for the vibration suppression of hoisting catenaries in super-deep mine hoists.
