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---本文来源于网络，仅供参考，勿照抄，如有侵权请联系删除---AbstractThecar'sperformancetoplayandroadconditionsadaptabilityarecloselylinked,thispaperdescribesindetailthevehicleperformanceevaluationindexcausesandcountermeasures,throughtheuseofscientificdataofvehicleperformanceandroadformula,summarizedthesituationandcharacteristicsofanalysis,webelievethatthecar'sperformancetoplayandroadconditionsadaptabilitymainlydisplaysinperformance,fueleconomyandbrake,handlingstability,smoothandthroughsex,roadconditionalsohasthecomplexityanddiversity.Basedontheanalysisofthecarallaspectsofperformancecombinedwithcertainroadadaptabilitytestsforthecar'sperformanceofgreatnecessity.ThispaperintroducestheconcretesituationinChina,roadcarallaspectsofthepropertiesofresearch,accordingtotheperformanceofevaluationindexes,thispaperanalysesthecausesofourcountry,andtheperformanceandroadconditionsadaptabilityarepreliminarilydiscussed.Keywords:vehicleperformance,roadconditions,adaptiveresearch---本文来源于网络，仅供参考，勿照抄，如有侵权请联系删除---目录摘要...........................................................................................................................IAbstract...........................................................................................................................II目录...........................................................................................................................III1设计总则......................................................................................................11.1课题的......................................................................................................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........................
