张秀鹏中国汽车性能与我国道路状况适应性研究

湖北汽车工业学院毕业论文I摘要汽车性能的发挥与道路状况适应性有着紧密的联系，本文详细叙述了汽车性能的评价指标成因及对策，通过运用科学的数据公式对汽车性能与道路状况的特点进行归纳分析，认为汽车性能的发挥与道路状况适应性主要表现在动力性、燃油经济性、制动性、操控稳定性、平顺性以及通过性等方面，而道路情况又具有复杂性和多样性。通过对汽车各方面性能的分析研究，结合一定的路况进行汽车性能的适应性试验具有很大的必要性。本文通过介绍我国道路的具体现状，对汽车的各方面性能的特点进行研究，根据汽车性能的评价指标，分析其成因，并对我国汽车性能与道路状况适应性进行初步的探讨。关键词：汽车性能，道路状况，适应性研究湖北汽车工业学院毕业论文IIAbstractThecar'sperformancetoplayandroadconditionsadaptabilityarecloselylinked,thispaperdescribesindetailthevehicleperformanceevaluationindexcausesandcountermeasures,throughtheuseofscientificdataofvehicleperformanceandroadformula,summarizedthesituationandcharacteristicsofanalysis,webelievethatthecar'sperformancetoplayandroadconditionsadaptabilitymainlydisplaysinperformance,fueleconomyandbrake,handlingstability,smoothandthroughsex,roadconditionalsohasthecomplexityanddiversity.Basedontheanalysisofthecarallaspectsofperformancecombinedwithcertainroadadaptabilitytestsforthecar'sperformanceofgreatnecessity.ThispaperintroducestheconcretesituationinChina,roadcarallaspectsofthepropertiesofresearch,accordingtotheperformanceofevaluationindexes,thispaperanalysesthecausesofourcountry,andtheperformanceandroadconditionsadaptabilityarepreliminarilydiscussed.Keywords:vehicleperformance,roadconditions,adaptiveresearch湖北汽车工业学院毕业论文III目录摘要.......................................................................................................................................IAbstract..............................................................................................................................II目录.....................................................................................................................................III1设计总则...........................................................................................................................11.1课题的来源.............................................................................................................11.2设计背景.................................................................................................................11.2.1我国道路状况...............................................................................................11.2.2道路情况对交通事故的影响.......................................................................21.2.3我国汽车现状...............................................................................................32汽车性能的评价指标与道路状况.................................................................................42.1汽车的动力性.........................................................................................................42.1.1汽车行驶阻力...............................................................................................42.1.2汽车总体受力分析.......................................................................................42.2汽车的燃油经济性.............................................................................................102.2.1汽车燃料经济性的评价指标.....................................................................102.2.2实际路况下汽车燃料经济性试验方法.....................................................112.3汽车的制动性.....................................................................................................142.4汽车的操纵稳定性.............................................................................................152.4.1影响汽车操纵稳定性的因素.....................................................................162.4.2实际道路下汽车操纵稳定性的研究.........................................................172.5汽车的平顺性.....................................................................................................182.6汽车的通过性.....................................................................................................193我国汽车性能与道路状况适应性的综合分析..............................................................203.1主观评价法对汽车性能综合评价........................................................................203.2道路状况对汽车性能的安全性分析....................................................................213.3科学认识道路因素与汽车行驶安全的关系更新道路规划和设计观念.............22湖北汽车工业学院毕业论文IV4结论与展望.....................................................................................................................244.1结论.......................................................................................................................244.2存在的不足............................................................................................................244.3展望.......................................................................................................................25致谢....................................................................................................................................26参考文献............................................................................................................................27湖北汽车工业学院毕业论文11设计总则1.1课题的来源课题《中国汽车性能与我国道路状况适应性研究》一是依据湖北汽车工业学院2012届毕业论文选题范围确定的题目；二是依据当前中国汽车性能与我国道路状况都有了快速的发展，适应性具有一定研究前景。1.2设计背景2010年，我国汽车市场呈现高开稳走态势，产销量月月超过100万辆，平均每月产销突破150万辆，全年累计产销超过1800万辆，刷新全球历史纪录。加之中国公路到2010年底大致有400万公里，其中，高速公路里程达60302公里，一级公路有54216公里，到2010年底，全国公路路面铺装率达到60％。‘五纵七横’国道主干线已于20
