摘　　要：为研究无气囊式空气包的压力脉动衰减特性,以某无气囊式空气包为研究对象,采用RNG k-ε模型结合用户自定义函数(UDF)对无气囊式空气包进行内流场分析,得到空气包不同时刻的压力分布云图、速度分布云图以及压力脉动情况。分析结果表明:该空气包对压力脉动的衰减效果较好,衰减率可达到65%。分析结果可为进一步的设计优化提供参考。In order to study the pressure pulsation attenuation characteristics of airbag-free air bags,an airbag-free air bag was taken as the research object,and the RNG k-εmodel combined with the user-defined function(UDF)was used to analyze the internal flow field of the airbag-free air bag,and the pressure distribution cloud map,velocity distribution cloud map and pressure pulsation of the air bag at different moments were obtained.The analysis results show that the air bag has a good attenuation effect on pressure pulsation,and the attenuation rate can reach 65%,which provides a reference for further design optimization.
