摘要: 设计出一种新型环形安全气囊,并给出该环形气囊的折叠方法。以某客车为参照,建立了包括新型环形安全气囊的客车驾驶员侧约束系统。对未匹配气囊、匹配传统气囊以及匹配新型气囊工况下的驾驶员损伤数据进行对比分析,并对新型气囊的参数进行了优化设计。结果表明,采用新型气囊工况后,驾驶员头部和胸部的损伤值均至少减小36%,能够有效减轻客车正面碰撞事故中驾驶员头部和胸部的损伤。

Abstract: A new annular safety airbag was designed, and a new folding method of annular safety airbag model was developed. Taking a coach as reference, a driver side restraint system including the new annular safety airbag was established. Occupant injury data were compared and analyzed among the conditions of no airbag, the matching of traditional airbag and the matching of new airbag. Then the parameters of the new airbags were optimized. The results show that the driver's head and chest injury values decrease by more than 36% with matching the new airbag which may effectively reduce head and chest injuries in frontal collisions of coachs.

Key words: coach, safety airbag, computer simulation, dummy
