辽宁工程技术大学本科毕业设计（论文）\辽宁工大应用技术学院毕业论文汽车安全气囊的发展与应用姓名：刘振中指导老师:周大军专业：汽车检测与维修班级：08-1班辽宁工程技术大学本科毕业设计（论文）\I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。）安全气囊的作用即在碰撞的第一阶段和第二阶段之间，迅速在车内人员与汽车构件之间产生一个充满气体的气垫，在碰撞过程中通过气囊的阻尼排气等过程吸收乘员的动能，使碰撞的第二阶段得以减缓，以减轻碰撞对人员的伤害程度。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辽宁工程技术大学本科毕业设计（论文）\IIAbstractInChina,withDevelopmentofHighwayandimprovevehicleperformance,vehicledrivingfasterandfaster,especiallyascarownershipincreasedrapidly,moreandmorecrowdedtrafficandmanyotherfactors.....Carsafetyinrecentthelossofaccidentyearbyyear.Therefore,thevehiclesafetybecomesespeciallyimportant.Anautomotivevehicleintothesafetyofbothactivesafetyandpassivesafety.Activesafetyreferstotheabilityofvehiclestopreventaccident,thereareanti-lockbrakingsystem,brakeforcedistributionsystems.Passivesafetyintheeventofanaccidentisthecaseoftheconfigurationofthecartheabilitytoprotecttheoccupants.Atpresent,thereareseatbelts,safetycushion,theairbagcrash-typebodyandprotectionsystem(AirbagRestraintSystem)andsoon.(Hereinafterreferredtoas:airbags.)Theroleoftheairbaginthecollisionbetweenthefirstandsecondphases,therapidcomponentinthecarbetweenstaffandacarfilledwithgascushion,inthecollisiondampingexhaustthroughtheprocessofairbagoccupantabsorptionkineticenergy,sothatthesecondphaseofthecollisionmitigationtoreducethedegreeofimpactinjurytopersonnel.Airbagsarecaroccupants,passivesafetyprotectiondevice.Seatbeltinthepassiveprotectionofwhichplayamajorroleintheprocess,andairbagsareSupplementalRestraintSystem(SupplementalRestraintSystem),theSRS.Keywords:automobilepassivesafetyairbagsupplementalrestraintsystem辽宁工程技术大学本科毕业设计（论文）\目录0前言............................................................................................................................................11汽车安全的概述..........................................................................................................................21.1汽车安全...........................................................................................................................21.2安全带与安全气囊............................................................................................................21.3安全气囊的分类................................................................................................................32安全气囊系统的结构及工作原理...............................................................................................42.1安全气囊系统的组成.......................................................................................................42.2安全气囊系统的基本工作原理........................................................................................52.3安全气囊的工作过程.......................................................................................................53安全气囊系统部件的结构与原理...............................................................................................73.1碰撞传感器.......................................................................................................................73.1.1机械型碰撞传感器.............................................................................................83.1.2汞开关型碰撞传感器.........................................................................................103.1.3半导体型碰撞传感器.........................................................................................103.2电子控制单元...............................................................................................................103.3备用电源........................................................................................................................113.4故障指示灯.....................................................................................................................123.5安全气囊组件.................................................................................................................124安全气囊的应用........................................................................................................................134.1安全气囊的正确使用.....................................................................................................134.2安全气囊的检修，储存和运输.....................................................................................144.3安全气囊的缺陷.............................................................................................................155安全气囊的检测........................................................................................................................185.1SRS系统故障自诊断测试.............................................................................................185.2读取安全气囊系统故障代码.........................................................................................195.3注意事项........................................................................................................................215.4清楚安全气
