摘　　要：采用落锤作为加载装置对三种长度的钢质圆管进行了轴向冲击实验,得到了轴对称屈曲模态和整体失稳形式及冲击力时程曲线,讨论了实验中皱折出现在端部附近和较长壳渐近屈曲但较短壳整体失稳可能的原因。Axisymmetric buckling models, whole collapse and the time histories of impact force were observed by the experiment on dynamic buckling of steel cylindrical shells which with three different lengths under axial impact, this experiment was carried out using drop hammer as the - loading apparatus. The phenomenon that the wrinkles develop in the vicinity of the end and longer shell response as axisymmetric buckling models but shorter shell response as whole collapse was observed. The reasons of the phenomenon were discused.
