Analysis of a Hybrid Pump Controlled Hydraulic System Based on AMEsim

Hydraulic systems play a pivotal role across various industrial domains with unsatisfied energy efficiency. A hybrid pump-controlled asymmetric hydraulic cylinder drive system is put forward due to its notable advantages in energy utilization efficiency and low cost. Researchers conducted an exhaustive introduction and analysis of key components within this hydraulic system. By thoroughly understanding the functional characteristics of each component, researchers constructed a fundamental framework of the system and engaged in a simulation model system. The primary aim was to analyze the performance and stability of the system, and propose suggestions for future improvement. This study focused on the selection and schematic design of components such as valves, motors, hydraulic cylinders, and other system parts within the hybrid pump-controlled asymmetric hydraulic cylinder drive system. By utilizing the AMESim software, researchers performed a design of three-way four-port valves and developed a comprehensive hydraulic system diagrams, subsequently validating these designs by comparing with experimental results. The simulation and experimental results confirmed the rationality and feasibility of the proposed design scheme.
