Haul truck dump body optimization for autonomous shovel loading
To reduce the difficulty in autonomous loading operations,a mining haul truck dump body optimization method for payload balancing is constructed.Firstly,a differential iterative algorithm for reconstruction of material pile in dump body was built for calculation of center of gravity.Secondly,based on such calculation algorithm,the discrete element method(DEM)simulation for loading operation was constructed and validated.Thirdly,the influence of dump body structure on position of piled material gravity center was studied using DEM simulation experiments.At last,an optimization on dump body structure was accomplished with the object of payload balancing in cross section and the restraints of longitudinal payload distribution,safety and capacity.The comparison results indicate that the optimized dump body can generate more balanced payload distribution in extreme loading positions.Besides,it has larger loading area and higher operation efficiency.
