车辆与动力工程学院毕业设计说明书柴油动力SUV的整体设计摘要SUV是一种近年来迅速发展起来的车型，它是集越野、旅行、储物、牵引为一体的多功能用车。它既具备中高档轿车的舒适性，较高的越野性和安全性，又有运动感，便于日常生活、外出旅行和野外休闲。在本文中，通过收集国内外的各种资料确定了整车的各项参数，确定了本次设计的方案、汽车的形式和汽车的主要参数，并且选择了与所设计汽车匹配的发动机和车身形式，同时本文对汽车轮胎的选择也有一定的介绍。本文中确定了整车布置时各个方向上的基准线，并且对底盘各个部件的选择和布置、车身的内部布置和汽车的外形设计等方面也进行了说明。在本文的性能参数计算部分，主要进行了汽车动力性和经济性方面的计算，文中提出了汽车发动机的选择及经济性的计算方法。通过与各个部件总成的协调，得出了汽车的最小转弯半径。通过查阅相关的资料文献确定了汽车的接近角和离去角，但是由于缺少必要的资料和实验，本文中对汽车的通过性参数、操纵稳定性参数、制动性参数的计算不够全面。SUV是近年兴起的车型，其先天的节油优势和高的性价比必然会受到越来越多人的青睐，有广阔的发展前景。关键词：设计，底盘，外型,发展DIESEL-POWEREDSUVDESIGNABSTRACTSUVhavedevelopedrapidlyinrecentyears,itcombinescross-countrytravel,storage,tractionfortheintegrationofamulti-functionalcar.Itisbasedonmiddle-gradesedanscomfortable,highercross-countryandsafety,andwithasenseofmovement,easedailylife,ontravelandleisurefield.Inthispaper,Ideterminethedesignofthisprogramthroughcollecttheinformationathomeandabroad,Ideterminetheparametersofthevehiclet,intheformofvehiclesandvehicleparameters,andthechoiceofvehicledesignandmatchingengineandbodyforms,Meanwhile,inthispaper,thechoiceofautomobiletiresaresomewhatintroduced.Inthispaperidentifiedavehiclelayoutthebaselineatalldirections,andthevariouscomponentsofthechassisoptionsandsettings,body'sinternallayoutandappearanceoftheautomobiledesignisalsointroduced.Inthispapertheperformanceparameters,themajordrivingforcefortheautomobileandtheeconomy,Thispaperpresentsanautomobileengineandthechoiceofeconomiccalculation.Withtheassemblyofthevariouscomponentscoordination,thevehiclereachedtheminimumturningradius.ThroughaccesstotherelevantinformationtodeterminetheliteratureoftheautomobileandtheChajinguleftcorner,butduetolackofnecessaryinformationandexperimentation,Inthispaper,thevehiclethroughsexualparameters,handlingandstabilityparameters,brakingparametersofcalculationisnotcomprehensiveenough.InrecentyearstheriseofSUVmodels,inherentadvantagesofsavingandhighcostperformancewillbemoreandmorepeopleofallages,withbroadprospectsforfuturedevelopment.Keywords:design,cha
