Optimization the start-up mode of bucket elevator by criterion of mean rate of change efforts in traction body during clash on drive drum

Abstract

The oscillations of the structural elements, the drive mechanism and the traction body are minimized by optimizing the movement modes of the grain elevator during transient processes, which made it possible to increase its efficiency. Based on the chosen dynamic model, a mathematical model was created using the d'Alamber’s principle. The optimization process of the start-up mode of the bucket elevator was considered by the criterion of mean rate of change efforts in the traction body during clash on the drive drum. Found laws of motion for working branch, the tensioning drum and the drive drum which correspond to the optimal mode of movement of the bucket elevator.
