Енергетичні аспекти у визначенні ефективності роботи землерийно-транспортних машин

Abstract. The article deals with the energy aspects of assessing the efficiency of earthmoving and transport machines. Approaches to determining the energy potential of productivity are analyzed. The application of the energy method for assessing the efficiency of machines and their working bodies is substantiated, which allows optimizing the use of energy resources. Problem. The efficiency of earth-moving and transport machines largely depends on energy consumption. Historically, increasing the unit power of machines was considered a direct way to enhance productivity. However, practical experience has shown that without significant changes in the design of working equipment, proportional growth in performance is not achieved. Goal. The goal of this study is to develop criteria for assessing the efficiency of construction machinery based on energy parameters. The study aims to examine existing analytical approaches, introduce generalized indicators, and validate their effectiveness in practical applications. Methodology. The research employs analytical methods to evaluate energy potential and efficiency indicators of earth-moving and transport machines. The methodology involves defining energy potential performance indicators and their application to industrial tractors and other construction machinery. Results. The study introduces the concept of generalized energy potential productivity, enabling a more accurate assessment of machine efficiency across various operational conditions. It also highlights the advantages of an energy-based approach in comparing machines and evaluating the effectiveness of modular construction systems. Originality. This research contributes to the formation of an energy-based methodology for assessing construction machinery efficiency. The introduction of energy-based evaluation criteria provides an objective framework for optimizing machine design and operational performance. Practical value. The proposed approach allows for a more accurate assessment of construction machine efficiency, enabling better resource allocation, improved machine design, and enhanced energy savings. It can be applied in optimizing machine sets and modular technological systems to ensure maximum productivity with minimal energy consumption.
