摘要: 通过对缓冲气囊的刚度特性与初始内压之间关系的实验研究,发现能表明气囊刚度在工作行程内由非稳态转变成稳态的初始内压,将这一有特殊意义的初始内压命名为“特征内压”.本文研究了特征内压的意义,特征内压与气囊的结构、尺寸以及缓冲特性之间的关系.

Abstract: In this paper, a special pressure level, named characteristic pressure, at which the stiffness of the airbag is changed from linear to non-linear one, was found through experiment investigation on the relationship between the initial pressure and the stiffness of the airbag. In addition, the effect of structure, dimension and attenuation property on the characteristic pressure was studied.

Key words: airbag, characteristic pressure, attenuation
