Evaluation of energy saving effect of hybrid forklift and test of energy saving system

以内燃叉车节能为目的,设计了一种混合动力叉车的驱动与能量回收系统。以某型3t级内燃叉车为原型机,建立混合动力叉车系统的仿真模型并进行仿真分析。为了验证仿真结果,对混合动力叉车所采用的能量回收系统进行了试验研究。仿真与试验结果表明:在叉车标准工况下,混合动力叉车能实现20.8%的综合节能效果,其能量回收系统能实现34.6%的能量回收率。

To achieve energy saving effect for forklift truck, a system of hybrid forklift drive and energy recovery is designed. In order to theoretically analyze the forklift hybrid system and find out the effective approach, which can be used to achieve energy saving, a real 3.0 t forklift is adopted and the corresponding hybrid system simulation model is built. Many simulation tests are carried out to analyze the energy saving effect. To validate the simulation results further, an energy saving system is built. The simulation and test results show that, under standard working condition, the hybrid forklift can obtain the energy saving effect of 20.8 % and its energy resaving system can obtain energy resaving rate by 34.6 %.
