Research on Planetary Carrier Performance of Cutting Drum of Underground Coal Mining Machine
Taking MG1000/2500-WD large mining height coal mining machine as the research object,this paper introduces an optimized design scheme for planetary carrier.Based on the theory of multibody dynamics,a cutting dynamics simulation model of the coal mining machine was constructed using ADAMS software.The performance of the planetary carrier was comprehensively analyzed from two perspectives:Static analysis of the two-stage planetary carrier and fatigue life analysis of the planetary carrier,in order to confirm the weak points of the planetary carrier under stress.Based on this,the optimization design scheme of the planetary carrier was introduced.The optimized design scheme was applied to practical engineering,and the results showed that compared with before optimization,the comprehensive performance of the planetary carrier was effectively improved after optimization.
