摘要
采用有限元方法建立了舰艇内爆模型,仿真计算了不同壁厚舱室结构在反舰导弹战斗部内爆作用下的毁伤效应。结果表明,战斗部在舰艇舱室内内爆时,冲击波是对舰艇舱室造成毁伤的主要因素,在舰艇舱室角隅部位,由于冲击波的反复叠加,造成的毁伤更为严重;同时,舰艇舱室的焊接质量是影响舱室结构强度的重要因素。
The FEA model of wareship in inner explosion was founded, different thickness cabins＇ damaged effect were simulated. Results indicated that the shock wave was the primary damage factor when the antiship missile warhead explosion in warship cabin, and the comer of warship cabin was the most damaged part because the shock wave was echoed in the comer, results also indicated that the jointing quality was important factor which affected the warship＇s structure intensity.
