汽车安全气囊的发展与应用
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( Airbag Restraint System)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(Supplemental Restraint System),即SRS。
关键词:汽车被动安全辅助约束系统安全气囊
Abstract
In China, with Development of Highway and improve vehicle performance, vehicle driving faster and faster, especially as car ownership increased rapidly, more and more crowded traffic and many other factors ... .. Car safety in recent the loss of accident year by year. Therefore, the vehicle safety es especially important. An automotive vehicle into the safety of both active safety and passive safety. Active safety refers to the ability of vehicles to prevent accident, there are anti-lock braking system, brake force distribution systems. Passive safety in the event of an accident is the case of the configuration of the car the ability to protect the occupants. At present, there are seat belts, safety cushion, the airbag crash-type body and protection system (Airbag Restraint System) and so on. (Hereinafter referred to as: air bags.)
The role of the airbag in the collision between the first and second phases, the ponent in the car between staff and a car filled with gas cushion, in the collision damping exhaust through the process of airbag occupant absorption ic energy, so that the second phase of the collision mitigation to reduce the degree of impact injury to personnel. Airbags are car occupants, "passive safety protection device." Seat belt in the passive protection of which play a major role in the process, and airbags are Supplemental Restraint System (Supplemental Restraint System), the SRS.
Key words: automobile passive safety airbag su
