摘　　要：将安全气囊织物视为多孔薄膜,基于Porous Jump模型对其动态透气性进行非稳态数值模拟,得到了测试管道中的流场分布情况,并最终得到安全气囊织物动态透气量.利用自行设计的安全气囊织物动态透气装置对其动态透气的数值模拟结果进行验证,结果表明数值模拟结果与实验结果吻合.The airbag fabric was regarded as porous medium. Based on the porous jump model,the fluid field distribution in the testing pipe was simulated,and the dynamic permeability of airbag fabric was obtained by unsteady numerical simulation. The results of numerical simulation of dynamic permeability were verified by dynamic permeability test using the tester designed by the authors. It was found that the dynamic permeability of airbag fabric resulted from the simulation agreed well with the experiment data.
