【正文】 周勐：混聯(lián)式電動(dòng)汽車再生制動(dòng)系統(tǒng)實(shí)驗(yàn)臺(tái)設(shè)計(jì) 34 結(jié)論與展望 再生制動(dòng)理論技術(shù)是混合動(dòng)力汽車的關(guān)鍵技術(shù)之一，其控制系統(tǒng)的研究比 較復(fù)雜，而我國(guó)關(guān)于這方面的研究與開(kāi)發(fā)尚處于起步階段，還有很多關(guān)鍵問(wèn)題 亟待解決。 在混合動(dòng)力汽車再生制動(dòng)系統(tǒng)的研究方面，本文只能說(shuō)是拋磚引玉，僅僅分析了電動(dòng)汽車再生制動(dòng)的原理和方法，進(jìn)行了試驗(yàn)臺(tái)方案的設(shè)計(jì)，繪制出核心部件的三維模型等，該方向的研究仍然任重道遠(yuǎn)，還有許多有待深入研究的工作。 根據(jù)本次畢業(yè)設(shè)計(jì)所做的工作，提出以下兩點(diǎn)展望： (1)從生產(chǎn)和裝配的角度出發(fā)，要盡量使再生制動(dòng)系統(tǒng)對(duì)車輛整個(gè)傳動(dòng)系統(tǒng)影響最小，以達(dá)到安裝更方便、通用性更強(qiáng)、適用范圍更廣的目的。 (2)從制動(dòng)新技術(shù)的角度出發(fā)，考慮用電磁場(chǎng)原理革新再生制動(dòng)技術(shù)。從能量轉(zhuǎn)換角度出發(fā)?？梢钥紤]將這部分制動(dòng)動(dòng)能轉(zhuǎn)化為易于再生的電磁能。從電機(jī)制動(dòng)方式得到啟示，電磁場(chǎng)原理可應(yīng)用于汽車制動(dòng)，即：在制動(dòng)過(guò)程中車輪作為電動(dòng)機(jī)給電機(jī)反相電壓，使車輪產(chǎn)生一個(gè)與轉(zhuǎn)動(dòng)方向相反的電磁力矩，從而達(dá)到減速停車的目的。這符合能量守恒原理，理論上是可行的。它不再借助摩擦制動(dòng)，不需要摩擦制動(dòng)器，卻能有效回收利 用制動(dòng)能量，是再生制動(dòng)研究和探索的新方向。 安徽工程大學(xué)機(jī)電學(xué)院畢業(yè)設(shè)計(jì) 35 致 謝 本次畢業(yè)設(shè)計(jì)是在肖平老師的悉心指導(dǎo)下完成的。在我畢業(yè)設(shè)計(jì)的整個(gè)完成過(guò)程中，肖平老師百忙之中抽出時(shí)間定期指導(dǎo)畢，了解我的畢業(yè)設(shè)計(jì)進(jìn)度和所遇到的難點(diǎn)，予以積極建議和耐心指導(dǎo)，并盡可能地為我搜集了相關(guān)設(shè)計(jì)資料。肖老師不僅以其多年來(lái)在無(wú)級(jí)變速器領(lǐng)域積累的豐富研究經(jīng)驗(yàn)幫助指導(dǎo)我完成了原本相對(duì)困難的課題，使我對(duì)本課題的知識(shí)有了更透徹更深入的了解，而且，他嚴(yán)謹(jǐn)?shù)闹螌W(xué)態(tài)度、契而不舍的科研態(tài)度將繼續(xù)影響著我，使我受益終身。飲 水思源，我將永遠(yuǎn)牢記肖平老師的幫助和指導(dǎo)，并在今后的工作學(xué)習(xí)中效仿。在此，向肖平老師及其家人表示我最衷心的感謝。 在我完成畢業(yè)設(shè)計(jì)的過(guò)程中，閱讀了大量汽車專業(yè)人士的學(xué)術(shù)成果，在此表示感謝。 在制圖過(guò)程中，與同學(xué)共同鼓勵(lì)，互相支持。特別是謝思長(zhǎng)同學(xué)和張碩，我們是同一組跟隨肖老師做畢業(yè)設(shè)計(jì)的，謝思長(zhǎng)同學(xué)論文題目與我類似，我們經(jīng)常就肖老師布置的任務(wù)進(jìn)行交流、探討；張碩同學(xué)善于使用三維軟件，在最后的三維建模過(guò)程中，給與我極大的幫助，感謝你們的幫助，感謝同窗四載相伴走過(guò)的日子。 值此學(xué)業(yè)完成之際，對(duì)多年來(lái)一直辛苦養(yǎng)育 、全力支持我的父母表示最深的敬意。沒(méi)有老師的指導(dǎo)建議、同學(xué)的支持幫助和汽車專業(yè)前輩的經(jīng)驗(yàn)成果，我的畢業(yè)設(shè)計(jì)是不可能順利完成的。再次向所有曾經(jīng)給予我?guī)椭娜吮硎旧钌畹闹x意！ 周勐：混聯(lián)式電動(dòng)汽車再生制動(dòng)系統(tǒng)實(shí)驗(yàn)臺(tái)設(shè)計(jì) 36 參考文獻(xiàn) [1] 周云山 鐘勇 ， 汽車電子控制技術(shù) [M]，北京：機(jī)械工業(yè)出版社， 2020 [2] 汽車工程手冊(cè)編輯委員會(huì) 編 ，汽車工程手冊(cè) (設(shè)計(jì)篇 ) ,人民交通出 版社 ,2020 [3]王望予，汽車 設(shè)計(jì) [M]， 北京： 機(jī)械工業(yè)出版社 [4] 陳家瑞 ， 汽車構(gòu)造（下冊(cè) ） [M］ ， 北京： 機(jī)械工業(yè)出版社 [5] 王維平 張磊 宋錦 朱敏，電動(dòng)汽車開(kāi)關(guān)磁阻電機(jī)再生制動(dòng)發(fā)電系統(tǒng)研究 [J]，微電機(jī)，2020,06（ 1） :63— 65 [6] 王軍 申金升 .國(guó)內(nèi)外混合動(dòng)力電動(dòng)汽車開(kāi)發(fā)動(dòng)態(tài)及發(fā)展趨勢(shì) [J] 公路交通科技 ,2020,17(l):71 一 74 [7]趙金龍，再生制動(dòng)現(xiàn)狀及發(fā)展趨勢(shì) [D] 重慶大學(xué) 2020（ 11） [8]何仁汽車制動(dòng)能量再生方法的探討 [J]江蘇大學(xué)學(xué)報(bào) ,2020 [9]葛安林 .車輛自動(dòng)變速原理與設(shè)計(jì) [M].北京：機(jī)械工業(yè)出版社， 1993.

Moreover, as the energy of our earth being consuming, the environments being worse, humanity believe that they must save the world and save ourselves through some measurements. So different field people do their best to save energy and reduce the damage to the environment. So people working at automotive now are working not only at the fortability for consumers, but also at the saving energy, sustainable development, less polluting. I listen to lecture form Nissan, getting some information as follow. The history of the automobile begins as early as 1769, with the creation of steampowered automobiles capable of human transport. In 1806, the first cars powered by internal bustion engines running on fuel gas appeared, which led to the introduction in 1885 of the ubiquitous modern gasoline or petrolfueled internal bustion engine. Cars powered by electricity briefly appeared at the turn of the 20th century but largely disappeared from monality until the turn of the 21st century, when interest in low and zeroemissions transportation was reignited. And I learned some imagines for automotive. Potential future car technologies include new energy sources and materials, which are being developed in order to make automobiles more sustainable, safer, more energy efficient, or less polluting. Cars are being developed in many different ways. With rising gas prices, the future of cars is leaning towards fuel efficiency, energy savers, hybrid vehicles, battery electric vehicle and the fuel cell vehicle. Being autodriving, the cars do not need people to drive them by himself/herself, and no matter the driver is an older or a kid. And each family will own just one car. With only one dirver`s seat. Then the cars can be designed with less materials. So we can know that how important are strategies of one automotive cooperation. What should they do to have a better petition in future? I have some ments. First one also the most important is the talented personnel. From old times, technology has being the driving force for humanity to make progress with nature and history. And talent people drive technology going ahead. The professional standards of industrial psychologists require that any selection system be based on a job analysis to ensure that the selection criteria are jobrelated. The requirements for a selection system are knowledge, skills, ability, and other characteristics, known as KSAO39。s. . law also recognizes bona fide occupational qualifications (BFOQs), which are requirements for a job which would be discriminatory were they not necessary such as only employing men as wardens of maximumsecurity male prisons, or enforcing a mandatory retirement age for airline pilots, or a religious college only employing professors of its religion to teach its theology. The goal of personnel selection, as all business processes, is to ensure an adequate return on investment. In the case of selecti
