Dual-Pump Hydraulic Hybrid Excavator with Combined Common Pressure Rail and Valve-Controlled System

摘要：

　　To solve the low efficiency problem of hydraulic excavator,one type of Dual-Pump hydraulic architecture with combined Common Pressure Rail (CPR) and traditional valve controlled system is presented.Firstly,we analyze the energy consumption of excavator during one cycle to know the energy distribution among each actuator.Then,the Dual-Pump system is explained to design an easy to modify,cost efficient hydraulic hybrid excavator.Moreover,we focus on the boom system and construct the model.Finally,a simulation is created and the results illustrate that the proposed system can satisfy the design requirement.
