Facing the energy crisis and environmental problems, saving energy of hydraulic excavator is very important. This paper proposes a structure of hybrid hydraulic excavator as well as the control strategy. The system combines the advantages of STEAM system, IMV system and hydraulic transformer. The simulation is done by using AMESim software. From the simulation result, the proposed system can reduce...
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 hydraulic excavator as well as a control strategy...
Nowadays, energy crisis and pollution have become a serious problem in the world. Saving energy of construction machinery, especially the hydraulic excavator is very essential. Potential gravitational energy regeneration is an effective solution to reduce the energy consumption of the hydraulic excavator. This paper proposes a new hybrid hydraulic excavator boom system and designs a new control strategy...
