摘要
针对传统液压挖掘机回转系统能量损失严重的问题,提出并设计一套液压挖掘机回转制动能量回收系统。分析该系统工作原理,以及液压蓄能器的参数匹配,通过AMESim软件建立模型,并进行仿真分析。仿真结果表明:该回转制动能量回收系统使挖掘机回转系统的节能效率达到50%左右,蓄能器进行能量回收的效率达到66.9%,回收能量再利用效率为50.3%,实现了节能减排的目的。
The paper proposes a recovering system of swing braking energy, which is designed to reduce the energy loss in hydraulic excavatorg swing system. Furthermore, the principle of the recovering system and the parameters of hydraulic accumulator are introduced. The simulation model is built by AMESim, Simulation results shown that the hydraulic excavator equipped with the recovering system of swing braking energy can save about 50% energy compared with the traditonal hydraulic excavator. The energy recovery efficiency can reach to 66.9% with the hydraulic accumulator. The recovery energy＇s utilization efficiency also can achieve 50.3%. Thus, the recovering system meets the goal of energy-saving and emission-reduction.
