摘　　要：车辆翻滚事故中,乘员被抛出车外时的致死率很高,而使用侧气囊覆盖抛出路径能够有效降低乘员被抛出车外的概率。依据美国联邦机动车安全标准第226号《乘员抛出缓冲》(FMVSS 226),进行了107次侧气囊抛出缓冲试验,并分析试验失效情况。通过分析发现:导致试验失效的主要原因是侧气囊尺寸不足、刚性不足及气袋设计不合理,使得侧气囊钻出车外,进而导致试验失效。In vehicle rollover accidents,the fatality rate is high when the occupants are ejected out of the vehicle,side air bags that covered the ejection path can effectively reduce the probability of occupants being ejected out of the vehicle.According to the US Federal Motor Vehicle Safety Standard No.226 Ejection Mitigation(FMVSS 226),a total of 107 side airbag ejection mitigation tests were carried out,and test failures were analyzed.Through analysis,it is found that the main reasons leading to test failure are insufficientside airbag size,insufficient airbag rigidity,improper air bag design,as a result the side airbag drilling out of the vehicle,which leads to test failure.
