摘要
圆柱壳是海洋工程结构物和潜体中广泛采用的结构单元,为了研究其在物体撞击作用下的响应以及撞击角度对撞击响应的影响,文中采用大型非线性动态响应分析程序MSC.Dytran,分不同撞击角度,对双层圆柱壳结构受射弹撞击过程进行了数值仿真,研究分析了圆柱壳结构的损伤变形、能量吸收及撞击力的变化情况。文中的计算结果对圆柱壳结构物的抗撞击分析研究及合理的结构设计有参考价值。
Cylindrical shell structure is widely used in marine structure and submarine structure.In order to investigate the response of this structure under impact action and the effect of impact angle on response,the numerical simulation of a double cylindrical shell structure impacted by an object under different loading cases is carried out by MSC.Dytran,an analysis code for nonlinear,dynamic behavior of structure.The damage deformation and energy absorption of cylindrical shell structure as well as the impact force are analyzed in this paper.The results of the calculation are useful to the research and design work of cylindrical shell structure.
