【摘要】：改革開(kāi)放以來(lái),我國(guó)社會(huì)發(fā)展迅速,人民生活水平逐年提高。汽車作為生活中不可或缺的交通工具,在促進(jìn)社會(huì)經(jīng)濟(jì)發(fā)展、物質(zhì)繁榮和給人們帶去便捷的同時(shí),也帶來(lái)越來(lái)越嚴(yán)重的環(huán)境污染和能源短缺的問(wèn)題。純電動(dòng)汽車由于具有零排放、噪聲小和出色的操作體驗(yàn)等特點(diǎn),已獲得越來(lái)越多的重視。近年來(lái),世界各國(guó)政府出臺(tái)相關(guān)政策以刺激純電動(dòng)汽車市場(chǎng),各大車企也紛紛針對(duì)純電動(dòng)汽車投入大量資金進(jìn)行研究開(kāi)發(fā)�？梢�(jiàn),純電動(dòng)汽車的熱潮真的到來(lái)了。本文的研究目的是設(shè)計(jì)一輛純電動(dòng)四驅(qū)汽車,根據(jù)設(shè)計(jì)要求完成整車重要部件的匹配設(shè)計(jì)。然后在ADVISOR軟件中建立各模塊的仿真模型,并對(duì)ADVISOR進(jìn)行二次開(kāi)發(fā),得出仿真結(jié)果。最后完成純電動(dòng)四驅(qū)汽車的試制,再通過(guò)整車道路測(cè)試獲得性能參數(shù),并與仿真結(jié)果進(jìn)行對(duì)比,從而來(lái)評(píng)價(jià)純電動(dòng)汽車的動(dòng)力性能。本文首先介紹了純電動(dòng)汽車的發(fā)展背景、特點(diǎn)以及國(guó)內(nèi)外的研究情況,揭示了發(fā)展純電動(dòng)汽車的必然性。接著詳細(xì)闡述了純電動(dòng)汽車的基本結(jié)構(gòu)、工作原理和常用的驅(qū)動(dòng)布置形式,并設(shè)計(jì)出純電動(dòng)四驅(qū)汽車的動(dòng)力驅(qū)動(dòng)布置結(jié)構(gòu),并給出了整車和部件的參數(shù)。完成整車重要部件的參數(shù)匹配,并畫(huà)出整車的三維模型。建模仿真前需要車輛進(jìn)行受力分析,車輛行駛方向除了受驅(qū)動(dòng)力之外,還受到加速阻力、滾動(dòng)阻力、坡道阻力和空氣阻力,依據(jù)汽車的受力分析和動(dòng)力傳動(dòng)系統(tǒng)的參數(shù)便可以得出車輛的最大爬坡度、最大加速度最高車速和三個(gè)動(dòng)力性評(píng)價(jià)參數(shù),然后在ADVISOR2002仿真軟件中建立純電動(dòng)四驅(qū)汽車的車輛模型、車輪模型、電機(jī)模型、變速器、蓄電池模型和主減速器模型。由于ADVISOR2002只能適用于前輪驅(qū)動(dòng)汽車的缺點(diǎn),需對(duì)其進(jìn)行二次開(kāi)發(fā),先對(duì)純電動(dòng)四驅(qū)汽車進(jìn)行受力分析,并建立對(duì)應(yīng)出適合四輪驅(qū)動(dòng)的整車仿真模型。利用新建的模型和整車和部件參數(shù),對(duì)整車進(jìn)行動(dòng)力性能仿真,并得出對(duì)應(yīng)的仿真結(jié)果。最后一部分,首先是根據(jù)設(shè)計(jì),在安徽農(nóng)業(yè)大學(xué)機(jī)電工程園開(kāi)始試制所設(shè)計(jì)的車輛。接著通過(guò)實(shí)車在道路上的測(cè)試,實(shí)際測(cè)的動(dòng)力性能數(shù)據(jù)與計(jì)算機(jī)上仿真的數(shù)據(jù)進(jìn)行對(duì)比,存在一點(diǎn)誤差,但是并不影響仿真結(jié)果的正確性,同時(shí)也驗(yàn)證了經(jīng)過(guò)二次開(kāi)發(fā)的ADVISOR2002軟件針?biāo)尿?qū)型純電動(dòng)汽車仿真平臺(tái)的合理性。
[Abstract]:Since the reform and opening up, China's rapid social development, people's living standards have improved year by year. As an indispensable vehicle in life, automobile not only promotes social and economic development, material prosperity and convenience to people, but also brings more serious environmental pollution and energy shortage. Due to its zero emission, low noise and excellent operating experience, pure electric vehicle has been paid more and more attention. In recent years, governments all over the world have issued relevant policies to stimulate the pure electric vehicle market, and major car companies have also invested a lot of money in research and development of pure electric vehicles. Visible, pure electric car craze really arrived. The purpose of this paper is to design a pure electric four-drive vehicle and complete the matching design of the important parts of the vehicle according to the design requirements. Then, the simulation model of each module is established in ADVISOR software, and the simulation results are obtained by the secondary development of ADVISOR. Finally, the trial production of pure electric four-drive vehicle is completed, and then the performance parameters are obtained by road testing, and compared with the simulation results, so as to evaluate the dynamic performance of pure electric vehicle. This paper first introduces the development background, characteristics and research situation of pure electric vehicle at home and abroad, and reveals the inevitability of developing pure electric vehicle. Then the basic structure, working principle and common driving layout of pure electric vehicle are described in detail, and the power drive layout structure of pure electric four-drive vehicle is designed, and the parameters of the whole vehicle and parts are given. Complete the parameter matching of the important parts of the whole vehicle, and draw the three-dimensional model of the whole vehicle. In addition to driving force, the driving direction of the vehicle is subjected to acceleration resistance, rolling resistance, ramp resistance and air resistance before modeling and simulation. According to the force analysis of the vehicle and the parameters of the power transmission system, the maximum climbing degree, the maximum acceleration and the maximum speed of the vehicle and the three dynamic evaluation parameters can be obtained. Then the vehicle model of the pure electric four-drive vehicle is established in the ADVISOR2002 simulation software. Wheel model, motor model, transmission, battery model and main reducer model. Because ADVISOR2002 can only be used in front wheel drive vehicle, it is necessary to develop it again. Firstly, the force of pure electric four drive vehicle is analyzed, and the simulation model of the whole vehicle is established. The dynamic performance of the whole vehicle is simulated by using the new model and the parameters of the whole vehicle and components, and the corresponding simulation results are obtained. The last part, first of all, according to the design, in Anhui Agricultural University Mechanical and Electrical Engineering Park began to test the design of the vehicle. Then through the real vehicle on the road test, the actual measured dynamic performance data and the computer simulation data, there is a little error, but does not affect the correctness of the simulation results, At the same time, it also verifies the rationality of the simulation platform of ADVISOR2002 software needle four drive pure electric vehicle.
