气囊误作用路障试验在实验室内实施方案研究

The Research on Barricade Test Implementation Plan of The Airbags Misuse in The Laboratory

安全气囊是车辆被动安全系统重要部件,可靠性是气囊最重要的品质指标之一,安全气囊漏点爆、迟点爆、误点爆都会给车内驾乘人员造成极大的伤害。2014年,国家标准GBXXXX-XXXX《汽车安全气囊系统误作用试验的方法和要求征求意见稿》正式发布,而各厂商对其中路障试验测试方法的可重复性异议较大。经过大量研究,提出了路障试验在实验室内实施的试验方法,能够有效保证试验的精度与可重复性,较好的保证了试验条件的一致性,并用实验验证了试验方法的可行性与有效性。

Airbags are important parts of vehicle passive safety system. Reliability of airbags is one of the most important quality index. Missing,delay and misuse of the explosion of airbags will cause great damage to the drivers and passengers.The draft of the national standard GBXXXX-XXXX automobile airbag system misuse test methods and requirements was released in 2014;however,manufacturers dissent the repeatability of the barricade test method. After extensive research,the method of the barricade test in the laboratory is put forward,which effectively guarantees the accuracy,repeatability of test and also the consistency of test conditions. The feasibility and effectiveness of the method is verified by a misuse test.
