MATHEMATICAL MODELING AND EFFICIENCY EVALUATION OF A HYDROSTATIC REGENERATIVE BRAKING SYSTEM IN QUARRY DUMP TRUCKS

This article examines the issues of improving energy efficiency in dump trucks operating under quarry conditions. The importance of hydrostatic regenerative technologies based on the recovery of kinetic energy lost during braking is scientifically substantiated. The study analyzes energy flows by considering vehicle operating modes, load levels, and driving conditions. The potential for reducing energy losses through the application of regenerative systems is identified. The processes of energy storage in hydraulic accumulators and its efficient utilization are evaluated. The results demonstrate the potential to reduce fuel consumption, improve environmental performance, and decrease exhaust emissions.
