Abstract:

Aiming at the problem of heating and reliability of traditional energy recovery system， a potential energy interactive recovery system of excavator boom based on multiple hydraulic cylinders was designed， and its characteristics were researched. The working principle and energy characteristics of the boom potential energy interactive recycling system were analyzed. According to the operation characteristics of the 35 t excavator and the change of boom potential energy， the system parameters were designed based on the hydraulic cylinder and accumulator. Furthermore， the virtual simulation model of excavator energy recovery was established to analyze the operation characteristics and energy-saving efficiency of the system. Finally， an energy recovery system test platform was built to test the feasibility and energy efficiency characteristics of the system. The simulation and test results of single action of boom lifting show that， compared with the conventional excavator， the peak pressure of the main pump output of the energy recovery system is reduced by 57.8%， the energy-saving efficiency of the system is 51.5%， while the controllability of excavator remains good at the same time.
