中文摘要：

针对安全气囊起爆试验依赖气体发生器的问题，按照国内外安全气囊开发试验法规，采用冷气体压缩替代火药气体发生器的方法，开发了一种安全气囊模拟起爆试验装置。设计了展开装置并采用ANSYS软件对其强度及气密性进行了分析，利用Fluent软件分析了标定装置中密闭容器的形状对压力时间（p t）曲线的影响，并基于虚拟仪器技术开发了该试验装置的测控系统。最后，进行了两组不同型号安全气囊的模拟起爆试验，结果表明，该试验装置能迅速准确地展开安全气囊，从而验证了该试验方法的有效性和准确性。

英文摘要：

Aiming at the fact that the blasting test of airbag is depended on real inflators,accord-ing to the test regulations of airbag,a method of compressing cold gas to replace the pyrotechnic in-flators was used to develop a test device to simulate the blasting test of airbag.The deployment device used for airbag was designed,and the strength and gas tightness of this device was also analyzed by ANSYS.Meanwhile,the Fluent software was used to analyze the effect of the tank shape of the cali-bration device on the pt curve.A measurement and control system was developed based on the vir-tual instrument.Finally,two group airbags with different types were used to simulate the blasting test,the test results demonstrate that this test device can inflate the airbag rapidly and accurately, and the effectiveness and accuracy of the method were also validated.
