摘要：Hydraulic excavators, especially medium and large excavators, waste a lot of energy during the frequent lifting-lowering process of its boom. Recovery and regeneration the wasted energy is an important means to achieve energy saving and emission reduction of excavators. In this paper, a potential energy recovery and regeneration system based on a multi-cylinder structure working device is invented. Firstly, the theoretical analysis of the system, and the modeling and simulation research are carried out. Results show that under the same boom-single-action conditions, the energy-saving efficiency of the excavator equipped with energy recovery system can reach 33%, it has important reference significance for evaluating the energy efficiency of the new system.
