摘　　要：通过实验分析了边界条件对于轴向冲击作用下圆柱壳屈曲的影响。实验表明,边界条件不同,圆柱壳的屈曲模态也不同,实验中得到的冲击力时程曲线和屈曲模态相互对应,其一致性令人满意。The effects of boundary conditions for the dynamic buckling behavior of cylindrical shells is analyzed under axial impact through an experimental investigation. The investigation indicates that cylindrical shells would have different bulkling modes as under different boundary conditions. The consistency between force-time curves and bulkling modes is quite satisfactory.
