Modelling and Dynamic Characteristics for a Non-metal Pressurized Reservoir with Variable Volume

Abstract With the increasing demand to reduce emissions and save energy, hydraulic reservoirs require new architecture optimize their weight, space, volume. Conventional open are large, heavy, easily polluted, threaten operation of systems. A closed reservoir provides advantages small volume light compared reservoirs. In this study, a non-metallic pressure with variable is designed manufactured for closed-circuit The housing made rubber, Mooney-Rivlin model chosen based on rubber strain properties. FEA simulation performed using ANSYS Workbench obtain structural stiffness. major contribution establishment mathematical models reservoir, including equation changing height, flow equation, force balance explore output characteristics reservoir. Based these results, were built analyze Moreover, test rig conventional system was transformed into asymmetric preliminary verification experiments conducted it. results demonstrate that can absorb discharge oil supercharge pump inlet benefit operation. changes in displacements under different ratios frequencies obtained, which verified accuracy models. Owing its lightweight design volume, replace reservoirs, lays foundation future theoretical research
