摘要
以典型舰船舱室结构为目标,研究炸药水下爆炸载荷输出特征和舱室结构的动态响应特性。给出舱室水下爆炸实验的试验装置、测点布设,测量炸药水下爆炸的自由场载荷和舱室所受载荷,分析舱室所受爆炸载荷的作用特征,研究舱室结构在水下爆炸作用下的响应特征,并讨论药量、爆心距对舱室结构动态响应的影响。该研究可以为反舰导弹作用下舰船目标易损性评估提供技术支持,也可为舰船目标防护提供理论参考。
The output characteristic of the explosion load and the dynamic response characteristic of a cabin in underwater explosion were studied. With the typical cabin of some ships as the object, the testing apparatus and layout of the underwater explosion test points were determined. The free field pressure and the cabin’s wall pressure in the underwater explosion were measured, and the response characteristics of the cabin wall and the cabin structure to the explosion loads were analyzed. The influence of the explosive charge’s mass and the distance to explosive center on the structural dynamic responses of the cabin was discussed. This study is valuable for the damage assessment of the ship targets in missile attack.
