汽车安全气囊系统的结构研究与检修.doc

摘要 随着汽车的普及率不断上升，汽车事故也随之增加，世界上每年因汽车交通 事故造成了巨大的人员伤亡和经济损失，汽车安全性问题引起了各个国家的高度 重视。 实践表明安全气囊是乘员在汽车碰撞事故中重要、有效的保护设备，在欧 美等工业化发达国家已经成为轿车必备的安全装置。在我国，21世纪开始的新车基本上都安装了安全气囊。然而安全气囊开发水平差异及技术发展水平问题致 各汽车厂商安全气囊的保护效果参差不齐，安全气囊的保护效果有待大幅度的提 高。为此，本文对汽车安全气囊系统的原理及检修作了分析与探讨。 关键词：汽车；系统；结构；碰撞；检修 Abstract With the increasing of the percentage of car, car accidents are increasing. Huge casualty and economic loss are caused in car traffic accidents all over the world. Each country accords great importance the problem of car safety. Practice shows that in car collision accidents airbag is very important and effectual protection facility, which becomes essential safety device for car in European. In our country, after 21st century airbag has been fixed up in all of new cars. However, the problems of airbag produced by each car company research and development level lead that the protection effect which should be improved is not satisfied. Aiming at improving the protection effect of airbag.This article analyses and discuss the structure and maintenance of SRS.
