静液叉车能量回收利用系统研究

Research on Energy Recycling System of Hydrostatic Forklift

为了节约叉车在起步加速、举升下降和制动减速动作过程中能量损失,对传统叉车工作装置和行走装置的液压回路系统进行部分的改造分析,提出利用蓄能器将叉车下降势能和行车制动能进行回收利用的设计方案,并对液压系统的特性进行分析。利用AMESim软件对势能回收和制动能量回收液压系统进行建模与仿真,仿真结果表明:设计的液压系统方案符合实际工况要求,降低了能耗。

In order to reduce the energy loss of forklift in the process of starting up, lifting, descending and braking, the hydraulic system of the working device and walking device of forklift was analyzed for reformation. A plan of recycling energy in the process of descending and braking with an energy accumulator was proposed, and the performance of the hydraulic system was analyzed. The model of hydraulic system was built with AMESim, and the simulation result shows that the plan cuts the energy loss.
