Application of Hydraulic Transformer on Energy Saving for Boom System of Hybrid Hydraulic Excavator

Abstract:

Facing the energy crisis and environmental problems, saving energy of construction machinery, especially in the hydraulic excavator is very important. Regeneration of the potential energy is an effective solution to save energy. However, the conventional hybrid excavator can’t regenerate the potential energy. This paper proposes a new structure of boom system of hydraulic excavator as well as a control strategy. The focus of the paper is using hydraulic transformer to regenerate energy and reusing the regenerated energy. The simulation is carried out by the AMESim software. From the simulation results, this new system has a high efficiency for energy saving.
