Abstract:The energy saving of hydraulic excavators is always an essential research. An energy recovery system can effectively recover the boom potential energy and rotational kinetic energy. Based on the standard working cycle of hydraulic excavators, a dynamic programming (DP) control strategy for hybrid hydraulic excavators was proposed to recover the boom potential energy and rotational kinetic energy. The hybrid hydraulic excavator simulation model was built by Simulink software. The simulation results indicated th… Show more
