| 摘 要： | 提出一种基于激波管实验和理论的空气袋织物透气率的测试方法.实验中空气袋织物被固定在激波管低压段末端,与大气相通.当一道平面激波与织物相撞击时将被反射,与此同时会在织物前方形成一个高压,由于空气袋织物是一种多孔介质,此高压将导致透过织物的气流流动,此流动的流率,即透气率,可通过对反射激波速度的测试而计算得到. |
| 关 键 词： | 空气袋 织物 透气率 激波 激波管 |

| Abstract: | A method based on the shock tube experiment is proposed for measuring the permeability of airbag fabrics. An airbag fabric sample is mounted near the end of open driven section. When a plane shock wave impacts the airbag fabric, it will be reflected. Meanwhile, an increased pressure formed at the front face of the airbag fabric will lead to a flow through the fabric due to the permeable structure of airbag fabrics. The air permeability of airbag fabrics is thus determined by measuring the velocity of the reflected shock wave. |
| Keywords: | airbag fabric permeability shock wave shock tube |
