Study on the Effect of Different Operating Parameters on the Performance of Drum Cut-Offs
In order to further investigate the optimization strategy of the cutting drum performance of coal mining machine,the drum of MG500/1180-WD coal mining machine is taken as the research object,and the effects of different working parameters(including the angle of coal body joints,drum rotation speed,and hauling speed)on the cutting performance of the drum are clarified through three-dimensional modelling and simulation analysis,and the effects on the cutting performance of the drum under different working parameters(including coal body joint angle,drum rotation speed,and hauling speed)are clarified,and the reasonable working parameters suitable for the operation of the drum of this coal mining machine are determined by the single-factor analysis and multifactor analysis.After single-factor and multi-factor analyses,the reasonable parameter combinations suitable for the drum cutting operation of this coal miner are 30° coal body joint angle,40 r/min drum rotational speed,and 6.5 m/min haul-off speed,which will serve as the reference for the drum cutting operation of the subsequent coal miners.
