汽车与人类生活的关系论文题目有哪些英文怎么说

Electronic brakeforce distribution or EBD or EBFD is an automobile brake technology that automatically varies the amount of force applied to each of a vehicle's brakes, based on road conditions, speed, loading, Always coupled with anti-lock braking systems, EBD can apply more or less braking pressure to each wheel in order to maximize stopping power whilst maintaining vehicular [1][2] Typically, the front end carries the most weight and EBD distributes less braking pressure to the rear brakes so the rear brakes do not lock up and cause a [3]How ABS worksUnder heavy braking, vehicle wheels may lock- The anti-lock braking system (ABS) monitors wheel speeds and releases pressure on individual wheel brake lines, rapidly pulsing individual brakes to prevent lock- During heavy braking, preventing wheel lock-up helps the driver maintain steering Modern ABS has four individual brake lines for each wheel, enabling different braking pressure on different road For example, less braking pressure is needed to lock a wheel on ice than a wheel which on bare If the left wheels are on asphalt and the right wheels are on ice, during an emergency stop, ABS detects the right wheels about to lock and reduces braking force on the right wheels, helping to avoid lock-up and loss of vehicle How EBD worksAs per SAE technical paper #920646 - Buschmann et "The job of the EBD as a subsystem of the ABS system is to control the effective adhesion utilization by the rear The pressure of the rear wheels is approximated to the ideal brake force distribution in a partial braking To do so, the conventional brake design is modified in the direction of rear axle overbraking, and the components of the ABS are EBD reduces the strain on the hydraulic brake force proportioning valve in the EBD optimizes the brake design with regard to: adhesion utilization; driving stability; wear; temperature stress; and pedal "EBD may work in conjunction with ABS and Electronic Stability Control ("ESC") to minimize yaw accelerations during ESC compares steering wheel angle to vehicle turning rate using a yaw rate "Yaw" is the vehicle's rotation around its vertical center of gravity (turning left or right) If the yaw sensor detects more/less yaw than the steering wheel angle should create, the car is understeering or oversteering and ESC activates one of the front or rear brakes to rotate the car back into its intended For example, if a car is making a left turn and begins to understeer (the car plows forward to the outside of the turn) ESC activates the left rear brake, which will help turn the car The sensors are so sensitive, and the actuation is so quick that the system may correct direction before the driver ABS helps prevent wheel lock-up and EBD helps apply appropriate brake force to make ESC work

汽车与人们日常、汽车与科技、经济、社会发展的关系  汽车提高了速度,使人们的时间变得越来越快,加快了生活节奏和事件的发生,增加了对人们的心理的刺激,带了各种生活压力,导致现代社会心理的疲惫与紊乱。。  还是古代好啊,生活节奏很慢,人们有充足的时间进行思考。。  效率与压力并存,关系就是大大增加了文明之间交流的频度和广度。  汽车缩小了时间上的距离,拉近了空间上的距离。  汽车能给我们带来很多方便,现在汽车的价值也有很多档次,一切都跟我们的社会在不断的进步,科技高速不发展分不开,但私家车不段增加,我们的能源就会加速的减少,但到目前为止还没有真正的一种能够代替石油的能源,汽车不断增加,有利也有弊,我们要用全面的眼光看待这个问题,不能盲目  汽车是改变世界的机器用是作为人们的代步工具有了汽林的喜剧小品中领略到老爷车的 现代社会,汽车已经和人类的车,人类的自由活动半径大大增加笨拙可爱之处,又可以从现代电影生活密不可分了。  汽车制造是大规模生产的行业,具有规模经济效应  社会对汽车不断增长的 要求,促使汽车工业人日益繁荣。一辆汽车有上万个零件,由钢铁、有色金属、塑料、橡胶、玻璃、纺织品、木材、涂料等繁多材料制成;应用冶炼、锻造、锻压、机械加工、焊接、装配、涂装等许多工艺技术制成;涉及冶金、机械制造、化工、电子、电力、石油、轻工等部门,汽车的销售和营运还涉及金融、商业、运输、旅游、服务等第三产业。可以断言,没有哪个行业与汽车完全无关。汽车业是一个关联度非常大的产业,汽车产业自身发展的同时,还可以带动约150多个上下游产业,从而促进城市经济的发展。此外汽车工业也给社会带来许多机会----日本的汽车制造、销售、营运等行业职工占全国就业人数的1/9,美国和德国的这个比例更高,占1/6。汽车工业的发展无疑回促进个行业的繁荣兴旺,带动整个国民经济的发展。汽车工业一是经济利益很高的产业。在发达国家中,许多著名的汽车企业举足轻重,在世界500强企业的排行榜中均名列前茅,这些国家汽车工业的 产值约占国民经济总产值的7%~8%,占机械工业总产值的30%,其实力足以左右国民经济的动向。因此,世界各各发达国家几乎无一例外地把汽车工业作为国民经济的支柱产业。  我国的汽车工业起步较晚,1953年7月15日第一汽车制造厂在长春动工兴建。1956年10月,第一汽车制造厂开工生产,结束了我国不能制造汽车的历史。1953~1958年是中国汽车产业的创建阶段,长春第一汽车制造厂的建成是这一阶段的标志。这一阶段的特点为建设工作是在原苏联的全面援助下进行的,产品由苏联引进,工艺流程由苏联设计,主要设备由苏联提供,连厂房设计也是由苏联方面承担的。1968年第二汽车制造厂在湖北十堰动工兴建,1975年投产。这个阶段的汽车制造厂及其主要产品由于依赖国家提供原材料和报销全部产品,汽车企业“缺重少轻”、“轿车基本空白”的缺陷后来又因为文革的原因,汽车产量停滞不前。1958~1984 年是中国汽车产业的第二阶段。1958年左右,中苏关系恶化。中国汽车产业与其他经济部门一起进入自力更生的时期。在初步形成了自己的基础工业之后,我国各地纷纷仿造和试制了多款汽车,逐渐形成了几个较有规模的汽车制造厂。改革开放以后,我国汽车行业逐渐从计划经济走向市场经济,开始的蓬勃发展时期。通过引进先进技术和整车项目,已经建立了完整的汽车工业体系,随着国民经济的蓬勃发展和生活水平的提高,对汽车的需求愈来愈旺盛,中国迅速跃升为巨大的汽车市场。我国的汽车产量已跻身于世界生产大国的前列。但是,我国还不是汽车工业强国,我国的汽车工业水平仍然落后,汽车企业多而分散,竞争力不强,不能与汽车工业迅猛发展的形势相适应。  首先,基于相关行业对汽车工业的作用,由依附、被动到今天走到“台前”,是一种历史进步,汽车业界就不应该总是抱怨“环境不好”,而应该树立一种“在困境中培养坚强”的积极心态。这对整个汽车产业链的发展都是必要的,有益的。  其次,汽车媒体和专家们由此可以摆脱原有思维惯性,不再“就汽车说汽车”,而要从多方面、多角度、多侧面地研究如何迎接汽车社会的到来?如何认识汽车与汽车文化的关系?如何推动汽车与社会的可持续发展?汽车的普及和与之相关产业的发展将会给经济和社会可持续发展带来什么样的机遇和挑战?怎样促进经济和社会各项事业的协调发展?汽车进入更多普通市民生活后对城市建设和城市管理提出了哪些新要求?具体有哪些改良和改革措施?汽车文化的魅力将如何冲击或影响人们生活方式的改变?等等等等。否则,仅是在汽车降价呀、新车上市呀、怎样修车呀上面打转转,实在是肤浅而又“同质化”的,对整个汽车产业的推动也是十分有限的。

How Manual Transmissions Work by Marshall Brain ­If you drive a stick-shift car, then you may have several questions floating in your ­How does the funny "H" pattern that I am moving this shift knob through have any relation to the gears inside the transmission? What is moving inside the transmission when I move the shifter? When I mess up and hear that horrible grinding sound, what is actually grinding? What would happen if I were to accidentally shift into reverse while I am speeding down the freeway? Would the entire transmission explode? In this article, we'll answer all of these questions and more as we explore the interior of a manual Cars need transmissions because of the physics of the gasoline First, any engine has a redline -- a maximum rpm value above which the engine cannot go without Second, if you have read How Horsepower Works, then you know that engines have narrow rpm ranges where horsepower and torque are at their For example, an engine might produce its maximum horsepower at 5,500 The transmission allows the gear ratio between the engine and the drive wheels to change as the car speeds up and slows You shift gears so the engine can stay below the redline and near the rpm band of its best Photo courtesy DaimlerChrysler Mercedes-Benz Actros, manual See more transmission Ideally, the transmission would be so flexible in its ratios that the engine could always run at its single, best-performance rpm That is the idea behind the continuously variable transmission (CVT) A CVT has a nearly infinite range of gear In the past, CVTs could not compete with four-speed and five-speed transmissions in terms of cost, size and reliability, so you didn't see them in production These days, improvements in design have made CVTs more The Toyota Prius is a hybrid car that uses a CVT The transmission is connected to the engine through the The input shaft of the transmission therefore turns at the same rpm as the engine

汽车与人类的关系 在1705年,纽可门首次发明了不依靠人和动物来作功而是靠机械来作功的实用化蒸汽机。这种蒸汽机用于驱动机械,便产生了划时代的第一次工业革命。随着蒸汽驱动的机械即汽车的诞生,人类社会中便拉开了永无休止的汽车发展的序幕。 1769年,法国人NJ居纽(Cugnot)制造了世界上第一辆蒸汽驱动三轮汽车。到1804的年,脱威迪克(Trouithick)又设计并制造了一辆蒸汽汽车,这辆汽车还拉着十吨重的货物在铁路上行驶了7公里。 进入20世纪以后,汽车不再仅是欧洲人的天下了,特别是亨利福特(HeneryFord)在1908年10月开始出售著名的“T”型车时,这种车产量增长惊人,短短19年,就生气1500辆。此间的1913年福特汽车公司还首次推出了流水装配线的大量作业方式,使汽车成本大跌,汽车价格低廉,不再仅仅是贵族和有钱人的豪华奢侈品了,它开始逐渐成为大众化的商品。也是此时开始,美国汽车便成为世界宠儿,福特公司也因此成为名副其实的汽车王国。 汽车从出现到现在短短一百多年间,已经成为世界上最大的制造业,创造出巨大的社会财富,并且深刻地影响着人类社会的发展,更是发展成为一种独特的文化。深究其对人类社会的影响,是如此深刻且持续。汽车最初的出现在作为运输工具,这一属性一直未变。当社会在不断进步,人们渴望拉近人与人的距离,生产上的需要等一系列动力促使汽车成为这个时代的产物。通过不断的发明改进,汽车终于面世。这一庞大的机器怪物,伴着隆隆的呼啸声,拉开了工业革命的序幕,并且使这个社会插上翅膀,伴随着它转动的轮子,一直开向未来。 汽车替代了代步、马车等传统交通手段,最大的特点就是高速。它使两地的距离在时空上缩短了,促进了更多的交流。越来越多的信息得到传递,促进了社会的生产,更高的拉动了整个社会的上升。这种新式交通方式促进了商贸的来住,并产生了一系列的相关服务。 汽车的出现,不仅代表着一种新事物的出现,它引导着一种全新的经济模式,一个新兴产生的诞生。汽车最初是拉开了钢铁和煤炭的需求,制造汽车需要大量的钢铁,冶金产业得到空前的发展,并且直接地影响了煤炭采集。矿业面临巨大的市场,这一强大动力使人类不断开发矿产,从煤炭到石油,再到天燃气等,点燃了整个人类社会文明的曙光。围绕着汽车产生了一系列的新生产业,橡胶、玻璃、塑料等等产,这些供给对化工、能源、制造等行业的结构进行了一系列的深化。汽车业是一个关联度非常大的产业,汽车产业自身发展的同时,还可以带支150多个上下游产业的发展。涉及到金融、旅游、服务、运输等行业,提供了无数工作岗位。这个群体遍及制造、销售、营运等行业。在日本,这个人口比例约为1/9,而且欧美国家,这个比例就更高了。由汽车形成了一个巨大的产业圈,遍及社会各个层面,这条产业链在一百年间创造的财富比过去一千年累积的财富还多。它使人类进步的步伐越来越大,并且节奏越来越来快。 汽车最初出现,速度并不快,但是它是用外部动力代替了人力。如何提高速度及能源利用率成为提高汽车技术的头号问题。科学家致力于这个问题的钻研,汽车的速度越来越高了,已经可以达到四百多公里每小时,零到一百公里的加速也缩短到三点多秒。由此产生了动力学等学科。汽车能源一直是个备受关注的问题,尤其是能源紧缺并且污染严重的今天,能源已经起着决定汽车兴衰的关键。由传统的石油到新型的燃气,再到生物燃料,人类一直在不断尝试。新能源汽车的提出,更是在汽车业引起一阵狂潮。新能源汽车是指采用非常规的车用燃料作为动力来源(或使用常规的车用燃料,但采用新型车载动力装置),综合车辆的动力控制和驱动方面的先进技术,形成的技术原理先进、具有新技术、新结构的汽车。新能源汽车包括有:混合动力汽车(HEV)、纯电动汽车(BEV)、燃料电池汽车(FCEV)、氢发动机汽车以及燃气汽车、醇醚汽车等等。传统汽车产业在21世纪面临最大的选择就是能源的选择。能源紧缺,并且环境污染越来越严重,一系列严峻的问题迫使人类不断寻找新的出路,汽车这种机器怪物的未来,就决定在能源上面。备受关注的我国《汽车与新能源汽车产业发展规划》(2011 年~2020年)草案已经出炉。从目前透露出的《规划》细则看,中央财将投入上千亿元,支持节能与新能源汽车核心技术的研发和推广,从发展规划、消费补贴、税收策、科研投入、府采购、标准制定等方面,中国已经构建了一整套支持新能源汽车加快发展的策体系。在21世纪,人类共同寻找汽车的就出路,相信在不久的将来,新能源洗车将成为主流。 汽车引导着一种文化,这种文化就是汽车文化。汽车已经从单一的交通工具过渡到多身份的象征,虽然交通工具是其永恒求变的属性。各个汽车生产商在其发展过程中创造了独树一帜的汽车文化,耳熟能详的有通用公司、丰田公司、奔驰公司等等,它们不仅代表着一个商标,更代表着各自独特的文化品牌。例如上海通用汽车有限公司,其宗旨:依靠一支训练有素、富有使命感和团队精神的员工队伍,贯彻精益管理原则,注重不断学习和积极创新,安全地为顾客提供世界级的高质量产品和服务,使上海通用汽车成为面向21世纪、国内领先、国际上有竞争力的汽车公司。超级跑车、房车、豪华轿车、越野车等等,成为了不同阶级的象征。每一个阶层不同的文化,造就了他们不同的选择,而每个阶层又为这些汽车融入了他们独特的文化,在人与车的交融中,形成了汽车文化。在美国,开着路虎悍马的可能是娇小的女子,她们与强悍粗犷的汽车显得格格不入,但是就是这种强烈的反差,显示出她们渴望力量,希望保护自己的愿望。作为汽车用户中最充满激情的群体,青年人更喜欢超级跑车,SCC超跑俱乐部就是这样一个文化集合地。“开跑车不是为了炫富,只是一种生活方式”这是他们的理念。这个群体宣扬着一种独特的汽车文化,而他们,也正是中国超级跑车文化的一个顶级代表。汽车从日常走上了运动的舞台。从第一辆汽车被生产出来到第一次汽车比赛的举行只不过十年的时间。起初,汽车比赛的目的只是汽车生产厂家为了检查车辆的性能,宣传使用汽车的安全性和可靠性,因此汽车生产厂家积极资助,推销其产品。世界上最早组织汽车比赛是在1887年4月20日,有法国《汽车》杂志社主办。不过参赛的只有1个人,名叫乔尔基-布顿,他驾驶四人座的蒸汽汽车从巴黎沿塞纳河畔跑到了努伊伊现在的汽车赛已完全成为一种职业活动,出现了空前繁荣的局面。在赛车场,那些五彩缤纷的赛车,随着一声令下,竟相出发,开足马力冲向前方。车手门你追我赶的争先表演,赛车如万马奔腾一泻千里而过的彩场面非常壮观,这对20~30万的现场观众和数以亿计的电视观众来说极丰富刺激。汽车运动的魅力可以表现为以下几个方面:有助于改善汽车的性能; 是强化的道路实验;动态车展最佳广告;促进汽车大众化。汽车赛是集人与车为一体的综合较量。与通常的体育运动相比,汽车运动不仅是车手个人技艺、意志和胆量的竞争,而且是汽车设计,产品质量的角逐。这种独具特色的双重性运动,更能体现人类精英与高新科技最完美的结合,体现人类对自然的征服能力。随着我国汽车产业的快速发展,人们对汽车的理解和认识也在逐步加深,作为汽车产业链的下游环节,汽车运动产业近年来开始在国内落地生根。“热衷于汽车运动的人越来越多,除了喜欢观看汽车赛事外,中国职业车手的队伍也在迅速壮大,他们已经开始出现在国际顶级汽车赛事中。随着F1、GT这样的世界顶级汽车赛事相继落户中国,中国国内的各项汽车赛事近年来也风起云涌,诸如全国汽车拉力锦标赛、全国汽车场地越野锦标赛、全国卡丁车锦标赛等一系列赛车运动,已经在中国汽车运动联合会的年度赛程上被排得满满当当。尽管国内的汽车运动正在如火如荼地开展,但应该清醒地看到,目前我国的汽车运动还处于起步阶段,新中国刚一成立就决定发展自己的汽车工业,1953年第一汽车制造厂破土动工,这是中国有史以来第一次建设自己的汽车厂,毛泽东主席为奠基仪式亲自题写了“第一汽车制造厂奠基纪念”。1956年我国生产的第一辆汽车下线,毛主席又亲自为其命名———解放。 1956年是中国汽车史上令人难忘的一年。5月,第一汽车制造厂试制成功东风牌轿车,送往北京向党的八大”献礼,这是中国自制的第一部轿车。而我国的赛车生产上仍然大大的落后欧美国家,有没有形成强有力的竞争力,企业生产技术落后,品牌不行。而且我国还是一个发展中国家,而赛车是一项“烧钱”运动勿需质疑,资金成为赛车运动发展的最大瓶颈。无论是F1这样的国际赛事,还是AGF、CCC等亚洲赛事,是否有足够的赞助商和赞助金额是一支车队生存壮大,赛事顺利进行,推广达到预期效果的关键所在。技术是保障一个没有自身核心技术的车队或者厂商,是无法在赛车世界里觅得一席之地;同样,一个在汽车行业没有自主研发能力的国家,也是无法成为真正意义上的赛车大国。从这个角度来看,中国赛车运动较发达国家相比,一开始就多少有些“先天不足”,不具明显优势的核心技术已经成为制约中国赛车运动发展的最大障碍,且这种软肋并不能单纯依靠市场推广和商业运作来弥补。赛车是一项刺激的运动,是一项团体的运动。一支好的赛车队伍需要有好的驾驶员站在前线比赛,更需要有优秀的修理团队的配合,还要有好的设计师等等。站在车队幕后更是实力强大的公司企业,有着国家的支持。从一个赛车运动的发展甚至可以看出一个国家的经济,科学技术的发展状况等。这就是赛车的魅力与内涵。 汽车的速度越来赶快,使人们的步伐越来越快,但是,汽车在为人类带来方便的同时,也带来了隐患。每年因交通事故伤亡的人数越来越多,汽车安全问题成为一个至关重要的问题。实际上从汽车诞生那一刻开始,汽车安全技术就随着汽车技术的发展而发展,如今汽车安全技术早已经不仅仅是安全气囊安全带的简单应用,各种电子设备的介入使得汽车安全装置更加的智能化人性化。实际上对于汽车,每一个零部件都涉及到其安全性,其中不仅仅是那些我们熟知的电子设备,同时也包括汽车所采用的每一块钢板,每一个焊点甚至每个焊点的位置都影响着汽车安全。另外驾驶员的驾驶习惯、道路配套设施都是和安全紧密相关的。 而这些汽车安全性配置按照事故发生的前后基本可以分为主动安全和被动安全两大类,汽车的主动安全性是指事故将要发生时汽车防止事故发生的能力,而被动安全则是指事故发生时车辆保护成员和步行者,使损失降到最小的能力。 各个公司都致力提高自己产品的安全性,从安全带、安全气囊、儿童安全座椅到车轮防抱死制动系统(ABS)、牵引力控制系统(ASR)各种智能系统,汽车从结构上越来越智能化,设备自动化设备程度越来越高。抛开产品的安全性,汽车安全延伸到文化层次,遵守交通守则,良好的驾驶习惯,交通道德等等都影响着汽车安全的方方面面。人是主观体,在汽车具有安全保护设备的前提下,人的意味、素质都成为汽车安全的关键因素。普及汽车安全知识,提高文明交通意识,成为汽车时代社会刻不容缓的任务。 汽车的安全,更是涉及到自然的安全。越来越多的汽车,虽然满足了人类不断增长的需求,但是,汽车的数量激增,不断地与人类增土地,土地问题越来越严峻。汽车对环境的污染,也严重地影响着人类的安全。汽车对环境的影响: (1)汽车制造过程中的污染。汽车的塑料铸件中使用氟利昂作为发泡脱沫剂,氟利昂对臭氧层有破坏作用。另外,铅基涂料会造成铅污染;油漆溶剂的散逸也会造成污染等。 (2)汽车噪声。据统计,城市噪声中,交通运输噪声占75%,而汽车在交通噪声中占了85%。据调查,全国80%以上城市交通干道两侧的噪声超过72分贝;上海西藏路中百一店附近的噪声达2分贝,有人认为是世界上最喧闹的街道。 (3)汽车拥堵。由于汽车保有量剧增,交通堵塞已经成为世界各国大城市的顽疾。汽车拥堵降低整个社会的效率,而且加重了空气污染。汽车频繁启动、刹车和低速行车使尾气中氮氧化物、一氧化碳、碳氢化合物等污染物比正常行驶时多得多,大量拥堵的汽车废气集中排放,在距地面约5米处形成一个污染层,正在人的呼吸带附近,危害人体健康。 (4)公路、停车场和加油站的影响。公路建设使沿线的植被破坏、水土流失、占用农田耕地等。1998年,中国公路总长达128万千米,这些路网使4万平方千米土地丧失农业功能。中国现有耕地132万平方千米,仅占国土面积的5%。露天停车场除了占地外,还会改变城市的气流的方向和速率,加剧城市的热岛效应。 (5)汽车排放的尾气污染空气。以北京为例,大气污染物中,39%的一氧化碳、8%的碳氢化合物、2%的氮氧化物来自机动车的尾气。另外汽车需要消耗大量的石油,我国是人均石油资源缺乏的国家,汽车拥有量的快速增加造成了巨大的能源压力。2002年,我国年进口原油6500多万吨,已经占年消耗量的30%。由于有一部分汽车以液化气为燃料,所以液化气的消耗在过去5年中平均每年增长25%。 (6)汽车报废对环境的影响。在车辆拆卸、处理过程中会产生大量固体废弃物、废水、废油等。一方面占用大量土地,另一方面,废机油会随雨水漫流,污染周边环境。 如何解决这些问题,也是决定汽车行业命运的关键。 纵观历史,汽车促进人类社会的巨大进步,并引导着人类社会文明的前进。但是,在21世纪,人类生存环境受到严重的破坏,生存资源急剧下降。汽车的命运是兴是衰,却是备受制约。一方面,汽车必然存在于人类社会,另一方面,汽车必须告别传统的模式,新式汽车的出现是社会发展的要求。汽车与人类的关系,必将持续且相互影响。参考文献: 《汽车文化概论》陈燕,王昕彦 主编,人民交通出版社,2010-8-1 《汽车环境保护学》朱崇基,周有平,何文华 编著,浙江大学出版社,2011-1-1 《汽车工程手册2 环境与安全篇》日本自动车技术会 编,中国汽车工程学会组 译,北京理工大学出版社,2010-12-1 参考文献(百度文库)

是强化的道路实验;动态车展最佳广告;促进汽车大众化。汽车赛是集人与车为一体的综合较量。与通常的体育运动相比,汽车运动不仅是车手个人技艺、意志和胆量的竞争,而且是汽车设计,产品质量的角逐。这种独具特色的双重性运动,更能体现人类精英与高新科技最完美的结合,体现人类对自然的征服能力。随着我国汽车产业的快速发展,人们对汽车的理解和认识也在逐步加深,作为汽车产业链的下游环节,汽车运动产业近年来开始在国内落地生根。“热衷于汽车运动的人越来越多,除了喜欢观看汽车赛事外,中国职业车手的队伍也在迅速壮大,他们已经开始出现在国际顶级汽车赛事中。随着F1、GT这样的世界顶级汽车赛事相继落户中国,中国国内的各项汽车赛事近年来也风起云涌,诸如全国汽车拉力锦标赛、全国汽车场地越野锦标赛、全国卡丁车锦标赛等一系列赛车运动,已经在中国汽车运动联合会的年度赛程上被排得满满当当。尽管国内的汽车运动正在如火如荼地开展,但应该清醒地看到,目前我国的汽车运动还处于起步阶段,新中国刚一成立就决定发展自己的汽车工业,1953年第一汽车制造厂破土动工,这是中国有史以来第一次建设自己的汽车厂,毛泽东主席为奠基仪式亲自题写了“第一汽车制造厂奠基纪念”。1956年我国生产的第一辆汽车下线,毛主席又亲自为其命名———解放。 1956年是中国汽车史上令人难忘的一年。5月,第一汽车制造厂试制成功东风牌轿车,送往北京向党的八大”献礼,这是中国自制的第一部轿车。而我国的赛车生产上仍然大大的落后欧美国家,有没有形成强有力的竞争力,企业生产技术落后,品牌不行。而且我国还是一个发展中国家,而赛车是一项“烧钱”运动勿需质疑,资金成为赛车运动发展的最大瓶颈。无论是F1这样的国际赛事,还是AGF、CCC等亚洲赛事,是否有足够的赞助商和赞助金额是一支车队生存壮大,赛事顺利进行,推广达到预期效果的关键所在。技术是保障一个没有自身核心技术的车队或者厂商,是无法在赛车世界里觅得一席之地;同样,一个在汽车行业没有自主研发能力的国家,也是无法成为真正意义上的赛车大国。从这个角度来看,中国赛车运动较发达国家相比,一开始就多少有些“先天不足”,不具明显优势的核心技术已经成为制约中国赛车运动发展的最大障碍,且这种软肋并不能单纯依靠市场推广和商业运作来弥补。赛车是一项刺激的运动,是一项团体的运动。一支好的赛车队伍需要有好的驾驶员站在前线比赛,更需要有优秀的修理团队的配合,还要有好的设计师等等。站在车队幕后更是实力强大的公司企业,有着国家的支持。从一个赛车运动的发展甚至可以看出一个国家的经济,科学技术的发展状况等。这就是赛车的魅力与内涵。 汽车的速度越来赶快,使人们的步伐越来越快,但是,汽车在为人类带来方便的同时,也带来了隐患。每年因交通事故伤亡的人数越来越多,汽车安全问题成为一个至关重要的问题。实际上从汽车诞生那一刻开始,汽车安全技术就随着汽车技术的发展而发展,如今汽车安全技术早已经不仅仅是安全气囊安全带的简单应用,各种电子设备的介入使得汽车安全装置更加的智能化人性化。实际上对于汽车,每一个零部件都涉及到其安全性,其中不仅仅是那些我们熟知的电子设备,同时也包括汽车所采用的每一块钢板,每一个焊点甚至每个焊点的位置都影响着汽车安全。另外驾驶员的驾驶习惯、道路配套设施都是和安全紧密相关的。 而这些汽车安全性配置按照事故发生的前后基本可以分为主动安全和被动安全两大类,汽车的主动安全性是指事故将要发生时汽车防止事故发生的能力,而被动安全则是指事故发生时车辆保护成员和步行者,使损失降到最小的能力。 各个公司都致力提高自己产品的安全性,从安全带、安全气囊、儿童安全座椅到车轮防抱死制动系统(ABS)、牵引力控制系统(ASR)各种智能系统,汽车从结构上越来越智能化,设备自动化设备程度越来越高。抛开产品的安全性,汽车安全延伸到文化层次,遵守交通守则,良好的驾驶习惯,交通道德等等都影响着汽车安全的方方面面。人是主观体,在汽车具有安全保护设备的前提下,人的意味、素质都成为汽车安全的关键因素。普及汽车安全知识,提高文明交通意识,成为汽车时代社会刻不容缓的任务。 汽车的安全,更是涉及到自然的安全。越来越多的汽车,虽然满足了人类不断增长的需求,但是,汽车的数量激增,不断地与人类增土地,土地问题越来越严峻。汽车对环境的污染,也严重地影响着人类的安全。汽车对环境的影响: (1)汽车制造过程中的污染。汽车的塑料铸件中使用氟利昂作为发泡脱沫剂,氟利昂对臭氧层有破坏作用。另外,铅基涂料会造成铅污染;油漆溶剂的散逸也会造成污染等。 (2)汽车噪声。据统计,城市噪声中,交通运输噪声占75%,而汽车在交通噪声中占了85%。据调查,全国80%以上城市交通干道两侧的噪声超过72分贝;上海西藏路中百一店附近的噪声达2分贝,有人认为是世界上最喧闹的街道。 (3)汽车拥堵。由于汽车保有量剧增,交通堵塞已经成为世界各国大城市的顽疾。汽车拥堵降低整个社会的效率,而且加重了空气污染。汽车频繁启动、刹车和低速行车使尾气中氮氧化物、一氧化碳、碳氢化合物等污染物比正常行驶时多得多,大量拥堵的汽车废气集中排放,在距地面约5米处形成一个污染层,正在人的呼吸带附近,危害人体健康。 (4)公路、停车场和加油站的影响。公路建设使沿线的植被破坏、水土流失、占用农田耕地等。1998年,中国公路总长达128万千米,这些路网使4万平方千米土地丧失农业功能。中国现有耕地132万平方千米,仅占国土面积的5%。露天停车场除了占地外,还会改变城市的气流的方向和速率,加剧城市的热岛效应。 (5)汽车排放的尾气污染空气。以北京为例,大气污染物中,39%的一氧化碳、8%的碳氢化合物、2%的氮氧化物来自机动车的尾气。另外汽车需要消耗大量的石油,我国是人均石油资源缺乏的国家,汽车拥有量的快速增加造成了巨大的能源压力。2002年,我国年进口原油6500多万吨,已经占年消耗量的30%。由于有一部分汽车以液化气为燃料,所以液化气的消耗在过去5年中平均每年增长25%。 (6)汽车报废对环境的影响。在车辆拆卸、处理过程中会产生大量固体废弃物、废水、废油等。一方面占用大量土地,另一方面,废机油会随雨水漫流,污染周边环境。 如何解决这些问题,也是决定汽车行业命运的关键。 纵观历史,汽车促进人类社会的巨大进步,并引导着人类社会文明的前进。但是,在21世纪,人类生存环境受到严重的破坏,生存资源急剧下降。汽车的命运是兴是衰,却是备受制约。一方面,汽车必然存在于人类社会,另一方面,汽车必须告别传统的模式,新式汽车的出现是社会发展的要求。汽车与人类的关系,必将持续且相互影响。参考文献: 《汽车文化概论》陈燕,王昕彦 主编,人民交通出版社,2010-8-1 《汽车环境保护学》朱崇基,周有平,何文华 编著,浙江大学出版社,2011-1-1 《汽车工程手册2 环境与安全篇》日本自动车技术会 编,中国汽车工程学会组 译,北京理工大学出版社,2010-12-1 参考文献(百度文库)
