A Mathematical Modeling Approach to Improving the Energy Efficiency OF Hydraulic Drive Systems in Hydromeliorative Machines
Abstract
Hydraulic drive systems are widely used in hydromeliorative machines due to their high power density, operational flexibility, and reliability under harsh working conditions. However, a significant portion of energy losses in these systems occurs during operation, leading to reduced overall efficiency and increased эксплуатационные costs. This study presents a mathematical modeling–based approach to analyze and improve the energy efficiency of hydraulic drive systems used in hydromeliorative machinery. The research focuses on the development of analytical models describing pressure losses, flow rate variations, and power consumption within hydraulic drive circuits. Key performance parameters, including volumetric flow rate, system pressure, hydraulic power, and overall efficiency, are evaluated under different operating regimes. The proposed models account for hydraulic losses in pipelines, control valves, and actuators, enabling a comprehensive assessment of system behavior. Simulation and analytical results demonstrate that optimal selection of operating parameters significantly reduces hydraulic losses and improves system efficiency. The findings indicate that operating hydraulic drives close to their optimal pressure–flow conditions can lead to noticeable energy savings while maintaining stable performance. The proposed modeling approach provides a practical tool for designing and optimizing hydraulic drive systems in hydromeliorative machines, contributing to enhanced energy efficiency, improved reliability, and reduced operating costs.
