In order to decrease the overflow loss of the hydraulic excavator when it stopped rotating, a new type of recovering system for swing braking energy based on accumulator was put forward.The working principle of the recovering system was introduced in detailand the simulation models of the ordinary system and the recovering system were built by using the AMESim.The simulation results show the new recovering system can improve the stability of the system;the new system alsocan recycle part of the releasing energy when the upper body begins to brake and can use the energy to start the next swing. After calculating, the energy recovery efficiency of the system can reach to 53.1% and the recovery energy's utilization efficiency can achieve 72.5% in a whole working cycle.
