Research on the System of Boom Potential Recovery in Hydraulic Excavator
The failure of energy recovery with descending of regular hydraulic excavators boom causes heat release problem, disfunction, and accelerated wear. According to this issue, this paper proposes a hydraulic excavator boom potential recovery system based on accumulator-hydraulic motor-generator. The accumulator of the system stores potential energy from construction of boom hydraulic cylinder through energy recovery. Then the generator generates electricity by driving the hydraulic motor using the energy saved in the accumulator. Hydraulic excavator boom potential recovery is accomplished. System model is built using AMESim software;a simulation research about the Hydraulic excavator boom potential recovery system is studied. Both the theoretical analysis and simulation research show that the system is able to save energy by improving the efficiency of hydraulic excavator boom potential recovery.
