Abstract :
The traditional hydraulic excavator has some questions, so as energy waste, Environmental pollution. In this paper, The control strategy of Oil-electric hybrid excavator presented swing mechanism brake energy recovery system is investigated. Permanent magnet synchronous motor feedback system moving process was analyzed. The control strategy is verified, the results show that the scheme can effectively recover braking energy excavator and high energy conversion efficiency.
