METHOD FOR DETERMINING THE ENERGY-EFFICIENT LAW OF MINING DUMP TRUCK MOTION
The article describes an effective way to reduce energy costs on the cyclic route of mining dump truck. The method involves implementing software energy-optimal control of traction electric vehicles along the travel route. A method has been developed for determining the energy-efficient law of mining dump truck motion based on the optimization of the «path-speed» function. The optimization of the traction electromotors control law of mining dump truck during cyclic motion along a given trajectory with a fixed travel time was carried out using Richard Bellman’s dynamic programming method to ensure energy efficiency and traffic safety. Comparison of results with experimental data obtained during motion on the quarry was fulfilled. Conclusions confirming the reliability of the obtained law and the effectiveness of the developed method for determining the energy-optimal motion of a mining dump truck were made.
