| 摘 要： | 将圆柱壳受轴向冲击破坏等效为一均质圆柱的破坏, 给出了等效参数的确定方法, 从而使圆柱壳的破坏分析简化为一维问题。并根据弹性动力学基本理论给出了等效圆柱受的冲击力的一种计算方法, 进一步得到了冲击下的圆柱壳的位移关系。

| Abstract: | Under the assumption of the existence of an equivalent column which has the same failure behavior as the composite shells following axial impact, the failure of the shells was reduced to a one dimensional problem. An equivalent law was introduced in this paper. By means of the elastic dynamics theory, a simplified impact load was obtained, and then the dynamic radial displacements of the cylindrical shells were determined. |
