【摘要】：随着物流行业的不断发展,叉车这种物流主要机械车辆的社会生产量、保有量和需求量将会越来越高。但是石油的保有量在不断的减少,价格也在连年攀升,内燃叉车废气污染也非常的严重。内燃叉车的发展必然遭受不断的打击,进而影响物流行业的发展。燃料电池技术,作为一种高效、清洁、优质的动力源,已经引起了世界各国物流行业的广泛重视。燃料电池混合动力叉车,以燃料电池作为主要动力源,它将氢气与氧气化学反应的化学能直接转变为电能,通过驱动电机驱动叉车工作。它克服了内燃叉车的排放问题以及以蓄电池作为动力源的电动叉车续使里程短的缺点。与传统的内燃叉车比较,燃料电池混合动力叉车没有热机过程,也不受卡诺循环的限制,具有较高燃烧效率、无废气排放和无废料丢弃,以及无工作噪声的特点。同时也能保持传统内燃叉车的工作性能。与电动叉车相比,没有必要花几个小时为电池充电,只需要花几分钟的时间填补压缩氢气体就可储存很大的能量。文章对几种燃料电池电动车辆的基本结构进行逐一分析,确定一种燃料电池电动叉车驱动系统基本结构,并选定驱动模式。详细介绍了燃料电池的内部结构及其子系统工作机理。在整车能量控制策略上对比了开关控制和功率跟随控制的优缺点,根据实际需要建立了功率跟随控制策略作为本文叉车的控制系统。并在ADVISOR软件仿真平台上建立叉车驱动系统仿真模型。对ADVISOR软件中的燃料电池混合动力叉车驱动系统的各主要部件模型的结构和工作原理作了简单介绍。燃料电池混合动力叉车驱动系统的参数匹配是燃料电池混合动力叉车研究的主要工作。本文根据该车提出的各项动力性能指标,对叉车驱动系统的各主要部件(燃料电池、蓄电池组、电动机)进行选型。通过对各个燃料电池驱动系统的比较分析,本文建立以FC+B的燃料电池混合动力驱动系统机械叉车,使用ADVISOR进行动力性、燃料经济性仿真研究,比较仿真结果,确定了一个合理的匹配结果。
[Abstract]:With the development of logistics industry, the social production, quantity and demand of forklift truck, the main mechanical vehicle, will be higher and higher. But the amount of oil is decreasing, the price is rising year after year, and the pollution of internal combustion forklift truck is very serious. The development of internal combustion forklift is bound to suffer a constant blow, and then affect the development of the logistics industry. Fuel cell technology, as an efficient, clean and high quality power source, has attracted wide attention in the logistics industry around the world. The fuel cell hybrid forklift truck takes fuel cell as the main power source. It converts the chemical energy of hydrogen and oxygen chemical reaction directly into electric energy and drives the forklift truck by driving motor. It overcomes the emission problem of internal combustion forklift truck and the short mileage of electric forklift truck with battery as power source. Compared with the traditional internal combustion forklift, the fuel cell hybrid forklift does not have the heat engine process, nor is it restricted by the Carnot cycle. It has the characteristics of high combustion efficiency, no exhaust emission, no waste disposal, and no working noise. At the same time can also maintain the traditional internal combustion forklift performance. Compared with the electric forklift, it is not necessary to charge the battery for several hours. It takes only a few minutes to fill the compressed hydrogen to store a lot of energy. This paper analyzes the basic structure of several fuel cell electric vehicles one by one. The basic structure of a fuel cell electric forklift drive system is determined and the driving mode is selected. The internal structure of fuel cell and the working mechanism of its sub-system are introduced in detail. The advantages and disadvantages of switching control and power following control are compared in the whole vehicle energy control strategy. The power following control strategy is established as the forklift truck control system according to the actual needs. The simulation model of forklift drive system is established on the visual software platform. In this paper, the structure and working principle of main components of fuel cell hybrid forklift drive system in ADVISOR software are introduced. The parameter matching of fuel cell hybrid forklift drive system is fuel cell hybrid drive system. The main work of forklift truck research. In this paper, the main components of the forklift drive system (fuel cell, battery group, motor) are selected according to the dynamic performance index proposed by the vehicle. Through the comparison and analysis of each fuel cell drive system, this paper establishes the FC-B hybrid fuel cell drive system mechanical forklift, carries on the power performance, the fuel economy simulation research, the comparison simulation result with the ADVISOR, A reasonable matching result is determined.
