Abstract

In this paper; a 20-ton prototype compound hybrid excavator is presented which includes assisting electric motor; swing electric motor; a super capacitor pack; an engine and negative flow hydraulic system. The energy-saving principle of hybrid excavator is introduced as well. The development rules of power train which include parameter design rules of key components and hierarchical structure of control strategy of hybrid power system are presented. By developing the electric swing control strategy and power management algorithm; experiments show that the developed hybrid power system can significantly improve the fuel economy of the excavator
