潜艇典型结构在撞击载荷作用下动态响应的试验研究

针对潜艇典型结构单元（加筋平板和加筋圆柱壳）在受到撞击载荷作用下的损伤变形模式和撞击过程中结构的动态响应进行试验研究。研究结果表明：筋材的内置和外置对平板和壳体结构的损伤变形模式具有很大影响，但对加筋板和加筋圆柱壳模型结构整体的吸能特性并无太大影响；壳体结构与平板结构相比较，具有更好的吸能特性，平板结构具有更好的抗撞击能力。

Research on Dynamic Response Test of Submarine Typical Structure Unit＇s under Impact Load

The submarine typical structure units＇ （stiffened plate and stiffened cylinder shell） damage deformation mode under impact load and dynamic responses during the process of impact was studied experimentally. The results showed that the damage deformation mode of stiffened plate and stiffened cylinder shell is very sensitive to the out-fixed or inlaid stiffened, but their ability of absorbing energy is not so sensitive to the layout of reinforcements, while the shell structure has better ability of absorbing energy compared with the plate structure, but the plate structure has better impact stiffness.
