摘　　要：为了保障输氢管道的服役安全,并满足氢能领域的人才培养需求,该文研制了输氢管道极限承载与裂纹动态扩展实验平台,设计了水压和气压加载两种工作模式,并设置万帧高速相机记录裂纹扩展过程提升实验精度。通过对6061-T6铝合金和304不锈钢两种典型材质管道进行测试,结果表明实验平台可有效测量不同初始缺陷条件下管道的极限承载压力、裂纹扩展长度和瞬态速率。学生通过该实验平台可深入了解输氢管道瞬态失效行为,借助平台培养了学生的动手和分析解决问题的能力。In order to ensure the service safety of hydrogen transportation pipelines and meet the talent training needs in the field of hydrogen energy,an experimental platform for the ultimate bearing capacity and crack growth of hydrogen pipelines is developed.Two working modes of water pressure and air pressure loading are designed,and the crack propagation process is recorded by introducing a high-speed camera to improve the accuracy of the experiment.Experiments are carried out on two typical materials of 6061-T6 aluminum alloy and 304 stainless steel.The results show that the experimental platform can effectively measure the ultimate bearing pressure,crack propagation length,and transient rate of pipes with different initial flaw conditions.Through the experimental platform,students can have an in-depth understanding of the transient failure behavior of hydrogen pipelines,and cultivate their hands-on and problem-solving abilities.
