【摘要】：全球變暖日益加劇,大氣環(huán)境問題的不斷凸顯,人類健康受到的威脅增大,人類的活動是導(dǎo)致這些問題的罪魁禍?zhǔn)住Ｈ祟愒诓粩嗵綄で鍧嵞茉?混合動力技術(shù)作為降低尾氣排放、減少運行成本的有效手段,在乘用車、輕型卡車的應(yīng)用如火如茶。而貢獻(xiàn)了較高尾氣排放的礦用自卸車則一直沿用著效率較低的電傳動技術(shù),在能耗、效率、尾氣排放等指標(biāo)中表現(xiàn)較差。本文以300噸級礦用自卸車為研究對象,采用礦山實際道路特點提取的循環(huán)工況,對混合動力礦用自卸車能量管理策略、優(yōu)化設(shè)計以及清潔能源的應(yīng)用發(fā)展做出討論。旨在保證礦用自卸車動力學(xué)性能不損失的前提下,改善礦用自卸車的排放性能、削減礦用自卸車燃油成本。在完成柴油-電傳動和混合動力礦用自卸車建模工作的基礎(chǔ)上,針對混合動力礦用自卸車的能量管理問題分別采用了基于規(guī)則的能量管理策略和基于優(yōu)化的能量管理策略(包括等效燃油最小消耗法和動態(tài)規(guī)劃算法)。在基于規(guī)則的能量管理方法分析中,對比分析了礦用自卸車混合動力化對礦用自卸車排放性能、單位質(zhì)量礦石燃油成本的影響,并考慮了計入電池成本之后額外電池成本贖回時間以及計入電池及電池附件質(zhì)量之后的載重能力變化。同時,基于優(yōu)化的能量管理方法中為當(dāng)前混合動力礦用自卸車的零部件匹配做了最優(yōu)結(jié)果討論。采用DIRECT全局優(yōu)化算法,以燃油經(jīng)濟(jì)性和單位質(zhì)量礦石燃油成本為優(yōu)化目標(biāo)來完成優(yōu)化設(shè)計的初步討論。根據(jù)礦用自卸車循環(huán)工況特點,增加循環(huán)工況完成能力、電池初始與結(jié)束時刻SOC差值、加速時間以及整車滿載爬坡能力測試作為約束條件,分別以燃油經(jīng)濟(jì)性(L/duty cycle, L/100km, MPG)、單位質(zhì)量礦石燃油成本($/t)為目標(biāo)函數(shù),完成礦用自卸車設(shè)計階段的零部件參數(shù)匹配初步優(yōu)化討論,包括發(fā)動機(jī)額定功率、電池容量、驅(qū)動電機(jī)額定功率等參數(shù)。為了進(jìn)一步改善排放性能、降低單位質(zhì)量礦石燃油成本,并保證動力學(xué)性能不受損失,本文對礦用自卸車發(fā)動機(jī)天然氣與混合動力技術(shù)的結(jié)合做出討論。量化分析了天然氣化發(fā)動機(jī)對礦用自卸車爬坡能力的影響,采用混合動力方案解決天然氣發(fā)動機(jī)扭矩?fù)p失對礦用自卸車動力學(xué)性能的影響。并指出,串聯(lián)式的礦用自卸車傳動系結(jié)構(gòu)在天然氣發(fā)動機(jī)的控制應(yīng)用中能夠有較大優(yōu)勢。最終,天然氣混合動力礦用自卸車在排放性能、單位質(zhì)量礦石燃油成本指標(biāo)中,相比于目前柴油-電傳動礦用自卸車有較大改善,且動力學(xué)性能沒有任何損失。本文對礦用自卸車混合動力的動力學(xué)性能、排放性能以及燃油成本為目標(biāo)做出討論,為礦用自卸車的混合動力及其優(yōu)化設(shè)計提供理論依據(jù)及指導(dǎo)。
[Abstract]:Global warming is getting worse, atmospheric environmental problems are becoming more and more prominent, and human health is being threatened. Human activities are the main culprits that lead to these problems. Human beings are constantly searching for clean energy. Hybrid power technology, as an effective means to reduce exhaust emission and operation cost, has been used in passenger cars and light trucks as fire, while mine dump trucks, which contribute to higher exhaust emissions, have been using less efficient electric transmission technology. The performance of energy consumption, efficiency and exhaust emission is poor. In this paper, 300 ton mine dump truck is taken as the research object, and the energy management strategy of hybrid electric mine dump truck is adopted, which is extracted from the characteristics of mine actual road. Optimization design and application development of clean energy are discussed in order to improve the discharge performance of mine dump truck without losing the dynamic performance of mine dump truck. Reduce the fuel cost of mine dump truck. On the basis of the completion of diesel electric drive and hybrid electric mine dump truck modeling, In order to solve the energy management problem of hybrid mine dump truck, rule-based energy management strategy and optimization based energy management strategy (including equivalent fuel minimum consumption method and dynamic programming algorithm) are adopted respectively. In the analysis of the energy management methods of the. The effects of mixed power of mine dump truck on discharge performance of mine dump truck and fuel cost per unit mass of ore are compared and analyzed. The redeeming time of additional battery cost after taking into account the battery cost and the load capacity change after taking into account the quality of the battery and battery accessories are also taken into account. In the energy management method based on optimization, the optimal results of the parts matching of the current hybrid mine dump truck are discussed. The DIRECT global optimization algorithm is adopted. Taking fuel economy and unit mass ore fuel cost as the optimization goal to complete the optimization design, the preliminary discussion is made. According to the characteristics of the cycle conditions of the dump truck, the completion capacity of the cycle condition and the SOC difference between the initial and the end time of the battery are increased. The acceleration time and the full load climbing ability of the whole vehicle are taken as the constraint conditions. The objective function is the fuel economy L / duty cycle, L / 100km, MPGN, unit mass ore fuel cost / t, respectively. In order to further improve the emission performance, the parameters matching of components in the design phase of mine dump truck is discussed, including engine rated power, battery capacity, driving motor rated power and so on. Reduce fuel cost per unit mass of ore and ensure that dynamic performance is not lost, In this paper, the combination of natural gas and hybrid power technology of mine dump truck engine is discussed, and the influence of natural gas engine on the climbing ability of mine dump truck is analyzed quantitatively. The effect of torque loss of natural gas engine on the dynamic performance of mine dump truck is solved by using hybrid power scheme. It is pointed out that the transmission system structure of series mine dump truck can have a great advantage in the application of natural gas engine control. Compared with the present diesel-electric drive dump truck, the discharge performance and fuel cost per unit mass of the natural gas hybrid mine dump truck have been greatly improved. In this paper, the dynamic performance, emission performance and fuel cost of mine dump truck are discussed in order to provide theoretical basis and guidance for the optimization design of mine dump truck.
