Optimum Design of the Parameters of the Shearer Drum

To design high quality and efficiency cutting drum, taking the drum speed, traction speed, pick line distance and helix angle as design variables, reducing the cutting energy consumption and load fluctuation of the shearer drum as the objective function, establishes optimization design model of working parameters of shearer drum, and takes the MG300/700-WDK shearer as an example, carries out the optimization analysis and obtains the best working parameters. The feasibility and superiority of the optimized drum by LS-DYNA simulation and experiment, provides theoretical basis for the improvement and optimization of the cutting drum structure.
