Summary:For the high energy consumption and poor emission of a medium-sized hydraulic excavator, energy consumption point is analyzed combined with the advantages of the electric hybrid system. The energy recovery schematic of the system is designed. Mathematical models of the slewing system are established and theoretical simulation is conducted, and it is compared with the traditional structure. The velocity, displacement, and energy consumption curves of the two systems are concluded under the same conditions. The comparison shows that: energy saving of the electric hybrid slewing system is 37.27% compared with the traditional system. And the electric hybrid slewing system has the characteristics of the better control function and the higher energy utilization.
