| 摘 要： | 通过对水下爆炸载荷的分析和已有动态稳定性判别准则的对比,提出适合于水下爆炸的动态稳定性判别准则:基丁药量的B-R准则、基于爆距的B-R准则和基于新型冲击因子的B-R准则.利用该准则计算了某型舰在水下爆炸中舱壁结构的动态稳定性.计算发现气泡脉动载荷在舱壁动稳性中是不可忽视的,且水下爆炸中结构的稳定性分为3个阶段.

| Abstract: | Through the comparisons between the analysis of the underwater explosion loads and the existing criterions,criterions for judging the dynamic stability in underwater explosion are presented,including the B-R criterion based on the charge weight,the B-R criterion based on the standoff distance and the B-R criterion based on the new impact factor.The dynamic stability of the bulkheads of a certain warship is calculated with these criterions,it is found that the bubble pulsating loads cannot be ignored in the ... |
