摘要
为了有效地提高液压挖掘机在实际工作时的能量利用率,提出了一种基于蓄能器设计的动臂势能回收再利用系统。分析储能系统的工作原理,构建了对应AMESim模型,研究了蓄能器自身的充气压力、体积及动臂下降速度等参数对能量回收率存在的影响,然后通过特定实验的方式检验该设计的可行性,即通过设置合适的蓄能器参数可实现有效的能量回收。该方案在本次实验的一个工作循环中可以回收52.3 J的能量,即液压泵的节能率能够达到35%,如果将其应用于大吨位挖掘机实现能量回收,则能实现客观的效益。
In order to effectively improve the energy utilization rate of hydraulic excavator in actual operation,a boom potential energy recovery and reuse system based on accumulator design is proposed.The working principle of the energy storage system was analyzed,the corresponding AMESim model was constructed,the influence of the accumulator's own inflation pressure,volume and boom descent speed on the energy recovery rate was studied,and then the feasibility of the design was tested by specific experiments,that is,effective energy recovery could be achieved by setting appropriate accumulator parameters.The scheme can recover 52.3 J of energy in one working cycle of this experiment,that is,the energy saving rate of the hydraulic pump can reach 35%,and if it is applied to a large-tonnage excavator to achieve energy recovery,objective benefits can be achieved.
