摘　　要：为最大限度地挖掘液压挖掘机的可回收潜能,以某公司8 t级液压挖掘机为研究对象,开展了液压挖掘机各执行机构可回收能量大小研究。基于液压挖掘机各执行机构工作原理,建立了挖掘机机械结构及可回收能量液压系统模型。以液压挖掘机国际通用标准工作循环,仿真分析了挖掘机各执行机构可回收能量大小,并通过试验验证了数学模型及仿真结果的正确性。研究结果表明:标准工作循环,液压挖掘机动臂、斗杆及回转机构可回收能量分别为33.21、11.76和18.74 k J,为液压挖掘机能量回收系统的开发提供了理论基础。In order to develop the maximum energy-saving potential of the hydraulic excavator,the recoverable energy amount of job device of hydraulic excavator was studied for an 8-ton hydraulic excavator. The mechanical structure and recoverable energy system of the hydraulic excavator was built based on the working principle of job device in the hydraulic excavator. The recoverable energy amount of job device of hydraulic excavator was analyzed using to the MATLAB / Sim Mechanics modules on the basis of the international standard working cycle of hydraulic excavator,and the simulated results were verified via the experiment. The results shows that the recovery energy of boom,arm,slewing mechanism are 33. 21,11. 76 and 18. 74 k J respectively in the standard working cycle,which provides the theoretical foundation for the development of energy recovery system of hydraulic excavator.
