【摘要】:隨著物流行業(yè)的不斷發(fā)展,叉車這種物流主要機(jī)械車輛的社會(huì)生產(chǎn)量、保有量和需求量將會(huì)越來越高。但是石油的保有量在不斷的減少,價(jià)格也在連年攀升,內(nèi)燃叉車廢氣污染也非常的嚴(yán)重。內(nèi)燃叉車的發(fā)展必然遭受不斷的打擊,進(jìn)而影響物流行業(yè)的發(fā)展。燃料電池技術(shù),作為一種高效、清潔、優(yōu)質(zhì)的動(dòng)力源,已經(jīng)引起了世界各國(guó)物流行業(yè)的廣泛重視。 燃料電池混合動(dòng)力叉車,以燃料電池作為主要?jiǎng)恿υ?它將氫氣與氧氣化學(xué)反應(yīng)的化學(xué)能直接轉(zhuǎn)變?yōu)殡娔?通過驅(qū)動(dòng)電機(jī)驅(qū)動(dòng)叉車工作。它克服了內(nèi)燃叉車的排放問題以及以蓄電池作為動(dòng)力源的電動(dòng)叉車?yán)m(xù)使里程短的缺點(diǎn)。與傳統(tǒng)的內(nèi)燃叉車比較,燃料電池混合動(dòng)力叉車沒有熱機(jī)過程,也不受卡諾循環(huán)的限制,具有較高燃燒效率、無廢氣排放和無廢料丟棄,以及無工作噪聲的特點(diǎn)。同時(shí)也能保持傳統(tǒng)內(nèi)燃叉車的工作性能。與電動(dòng)叉車相比,沒有必要花幾個(gè)小時(shí)為電池充電,只需要花幾分鐘的時(shí)間填補(bǔ)壓縮氫氣體就可儲(chǔ)存很大的能量。 文章對(duì)幾種燃料電池電動(dòng)車輛的基本結(jié)構(gòu)進(jìn)行逐一分析,確定一種燃料電池電動(dòng)叉車驅(qū)動(dòng)系統(tǒng)基本結(jié)構(gòu),并選定驅(qū)動(dòng)模式。詳細(xì)介紹了燃料電池的內(nèi)部結(jié)構(gòu)及其子系統(tǒng)工作機(jī)理。在整車能量控制策略上對(duì)比了開關(guān)控制和功率跟隨控制的優(yōu)缺點(diǎn),根據(jù)實(shí)際需要建立了功率跟隨控制策略作為本文叉車的控制系統(tǒng)。并在ADVISOR軟件仿真平臺(tái)上建立叉車驅(qū)動(dòng)系統(tǒng)仿真模型。對(duì)ADVISOR軟件中的燃料電池混合動(dòng)力叉車驅(qū)動(dòng)系統(tǒng)的各主要部件模型的結(jié)構(gòu)和工作原理作了簡(jiǎn)單介紹。 燃料電池混合動(dòng)力叉車驅(qū)動(dòng)系統(tǒng)的參數(shù)匹配是燃料電池混合動(dòng)力叉車研究的主要工作。本文根據(jù)該車提出的各項(xiàng)動(dòng)力性能指標(biāo),對(duì)叉車驅(qū)動(dòng)系統(tǒng)的各主要部件(燃料電池、蓄電池組、電動(dòng)機(jī))進(jìn)行選型。通過對(duì)各個(gè)燃料電池驅(qū)動(dòng)系統(tǒng)的比較分析,本文建立以FC+B的燃料電池混合動(dòng)力驅(qū)動(dòng)系統(tǒng)機(jī)械叉車,使用ADVISOR進(jìn)行動(dòng)力性、燃料經(jīng)濟(jì)性仿真研究,比較仿真結(jié)果,確定了一個(gè)合理的匹配結(jié)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.
