Numerical investigation was carried out on a cylindrical shell subjected to deep water blast wave by using ABAQUS software package. The simulation contained static analysis by using ABAQUS/Standard and dynamic analysis by using ABAQUS/Explicit, and the analysis result of the former was imported into the latter as the initial condition, and then the influencing factors of dynamic response of cylindrical shell were identified. The calculated results indicated that the dynamic response of cylindrical shell was influenced by depth, orientation of explosion and prestress. The damage and distortion of cylindrical shell increases with depth, and the velocity-time history of cylindrical shell particle becomes smoother as the depth increases. The dynamic response to different orientations of explosion is distinct. Prestress leads to severe damage and distortion of the cylindrical shell, which also relates to orientation of explosion. Research results are valuable in evaluating the vulnerability of submarines.

运用通用有限元程序ABAQUS,对圆柱壳在深水爆炸冲击波作用下的动态响应进行了数值模拟,研究了圆柱壳所处深度、爆心方位和预应力对于圆柱壳动态响应的影响。研究结果表明:在同样的水下爆炸冲击波作用下,随着深度的增大,圆柱壳的毁伤逐渐加重,而且响应过程中的变形逐渐增大,低频响应阶段的速度曲线趋于平坦;爆距不变时,不同的爆心方位在不同深度上的毁伤效果存在一定差异;预应力的存在使圆柱壳的毁伤加重,并且预应力对圆柱壳动态响应的影响与爆心方位有关。研究结果对于潜体结构的生命力评估具有一定参考价值。

运用通用有限元程序ABAQUS,对圆柱壳在深水爆炸冲击波作用下的动态响应进行了数值模拟,研究了圆柱壳所处深度、爆心方位和预应力对于圆柱壳动态响应的影响。研究结果表明:在同样的水下爆炸冲击波作用下,随着深度的增大,圆柱壳的毁伤逐渐加重,而且响应过程中的变形逐渐增大,低频响应阶段的速度曲线趋于平坦;爆距不变时,不同的爆心方位在不同深度上的毁伤效果存在一定差异;预应力的存在使圆柱壳的毁伤加重,并且预应力对圆柱壳动态响应的影响与爆心方位有关。研究结果对于潜体结构的生命力评估具有一定参考价值。

Numerical investigation was carried out on a cylindrical shell subjected to deep water blast wave by using ABAQUS software package. The simulation contained static analysis by using ABAQUS/Standard and dynamic analysis by using ABAQUS/Explicit, and the analysis result of the former was imported into the latter as the initial condition, and then the influencing factors of dynamic response of cylindrical shell were identified. The calculated results indicated that the dynamic response of cylindrical shell was influenced by depth, orientation of explosion and prestress. The damage and distortion of cylindrical shell increases with depth, and the velocity-time history of cylindrical shell particle becomes smoother as the depth increases. The dynamic response to different orientations of explosion is distinct. Prestress leads to severe damage and distortion of the cylindrical shell, which also relates to orientation of explosion. Research results are valuable in evaluating the vulnerability of submarines.
