阜新高等专科学校毕业论文汽车安全气囊故障的检测与维修姓名:张欢指导老师:闫石专业:汽车检测与维修班级:汽修09-1班摘要在我国,随着高速公路的发展和汽车性能的提高,汽车的行驶速度越来越快,特别是由于汽车拥有量的迅速增加,交通越来越拥挤…..等诸多因素导致近年来汽车安全事故的损失逐年上升。所以,汽车的安全性就变得尤为重要。汽车安汽车的安全性分为主动安全和被动安全两种。主动安全是指汽车防止发生事故的能力,主要有防抱死系统,制动力分配系统等。被动安全是指在万一发生事故的情况下汽车上的配置保护乘员的能力。目前主要有安全带、安全气垫、防撞式车身和安全气囊防护系统(AirbagRestraintSystem)等。(以下简称为:安全气囊。)安全气囊属于汽车乘员“被动安全性保护装置”。其中安全带在被动保护过程中起主要作用,而安全气囊属于辅助约束系统(SupplementalRestraintSystem),即SRS。关键词:汽车被动安全辅助约束系统安全气囊AbstractInourcountry,withthedevelopmentoftheexpresswayandimprovedcars,theautomobilespeedmoreandmorequickly,especiallybecauseoftherapidincreaseofcarownership,increasingtrafficcongestion....manyfactorssuchasthecause.Inrecentyearsautoaccidentlossisincreasingyearbyyear.Therefore,thesafetycarbecomesparticularlyimportant.Autosecuritycarsafetyintoactivesafetyandpassivesafetytwo.Activesecurityreferstothecartopreventtheoccurrenceofaccidents,mainlywithanti-lockbrakingsystem,thebrakingforcedistributionsystem.Passivesafetyreferstoincaseofaccidentvehicleconfigurationontheoccupantprotectionability.Atpresentthemainsafetybelt,safety,anti-collisionvehicleandairbagrestraintsystem(AirbagRestraintSystem).(hereinafterreferredtoas:theairbag.)SRSbelongstothevehicleoccupant"passivesafetyprotectiondevice".Thesafetybeltinpassiveprotectionplayamajorroleintheairbag,whichbelongstoasupplementalrestraintsystem(SupplementalRestraintSystem),namelySRS.Keywords:automobilepassivesafetyairbagsupplementalrestraintsystem汽车安全气囊故障的检测与维修一.汽车安全气囊的概述····································4二.安全气囊的工作过程····································6三.安全气囊故障的检测与维修······························73.1安全气囊系统故障诊断基本流程·························73.2安全气囊系统故障分析与检测························83.3和悦安全气囊的检测与维修·······················9结论·····················································12谢辞·····················································13参考文献·················································14附录·····················································15第1章汽车安全气囊的概述1.1安全气囊系统的作用和分类1.1.1安全气囊的作用安全气囊系统俗称SRS,是英文SupplementRestraintSystem的缩写,直译为辅助防护系统。由于安全气囊(SafeAirBag)是辅助防护系统的重要装置,所以人们用SRS表示为安全气囊系统。安全气囊的是最近发展起来的被动安全装置。它对驾驶员和乘员的头部,颈部安全有着十分明显的保护作用。特别是汽车正面碰撞和侧面碰撞时,其保护作用尤为明显。安全统计结果表明,汽车发生事故时,人体胸部以上受伤的机率高达75%以上,而座椅安全带对人体胸部以上的保护作用是十分有限。尤其是车速快时更是如此。在汽车发生冲撞时,安全气囊系统对保护...
