Structural optimization of the hydraulic drive of a mobile transport and reloading rope complex based on pareto-optimal solutions

Abstract

The article proposes a method of structural optimization of the hydraulic drive of mobile transport and reloading rope complexes based on special multi-axle chassis with increased carrying capacity and cross-country ability. At present, this type of technological machines can be considered as a new class of technological overground transport vehicles, which is an effective alternative to stationary freight ropeways for hard-to-reach areas with difficult terrain and, if necessary, the rapid deployment of transport and logistics operations. An algorithm for the formation of the Pareto set is considered, which consists of a variety of alternative versions of the hydraulic drive based on a combination of positive displacement pumps and hydraulic motors of permissible standard sizes. A criterion for choosing the Pareto-optimal solutions of the designed hydraulic drive is proposed, based on three quality indicators — the total mass of the hydraulic machines, the specific power and the efficiency of the hydraulic drive.
