Simulation Study on Different Energy Efficient Hydraulic System: An Overview

In this paper, a new hydraulic energy-regenerative model was offered from its application through modelling to its control. The model was constructed on a closed-loop hydrostatic transmission and used a hydraulic accumulator as the energy storage system invented in a new configuration to recover the kinetic energy without any return of the fluid flow. The displacement deviation in the secondary unit was reduced, increasing the uses of several types of hydraulic motor/pumps. The proposed system was modelled based on its physical features. The energy consumption and the influences on the energy-recovery potential of the system were analyzed. Simulation and experiments were performed to evaluate the validity of the employed mathematical model and the effectiveness of the control system.
