Vision-based transverse vibration displacement measurement of hoisting vertical ropes in mine hoists [PDF]
Advances in Mechanical Engineering, 2021 At present, there is no appropriate way to measure the transverse vibration response of moving hoisting vertical rope in hoist. Therefore, a vision-based measurement method combining the digital image correlation (DIC) and digital image processing (DIP) algorithms is proposed in this paper. In this method, a reference line perpendicular to the vertical

Dynamic analyses of hoisting ropes in a multi-rope friction mine hoist and determination of proper hoisting parameters [PDF]
Journal of Vibroengineering, 2016 To avoid the failure of rope collision caused by large amplitude transverse vibrations, this study aimed to determine proper hoisting parameters of a multi-rope friction mine hoist. To explore dynamic behaviors of the hoisting catenaries with constant length and the vertical hoisting ropes with variable length which are both subjected to the periodic ...
