基于改进的接触爆炸毁伤模型的航空母舰不沉性评估

The Floodability Assessment of Aircraft Carriers Based on a Modified Contact Explosion Damage Model

针对传统航空母舰不沉性评估时采用指定破损舱组和校核规范无法对破损航空母舰生存能力给出定量评价的问题,首先建立基于单发和双发武器接触爆炸的毁伤模型来模拟舱段在武器毁伤中的破损,并在假定第1发毁伤参数固定的情况下,仿真计算破损航空母舰的浮态随第2发毁伤位置在全舰纵向和垂向变化的响应曲面,然后从满足校核规范和考虑海浪对破损航空母舰的不利影响两方面建立毁伤航空母舰的残存概率模型,可以对航空母舰在不同武器毁伤下的生存能力给出定量评价。该方法可以作为航空母舰方案设计阶段不沉性设计与评估的方法和手段。

The traditional floodability assessment method of aircraft carrier often requires artificial specification of the damage cabins and cannot provide the survival capability analysis of damaged ships. Aiming at the problem, the one-hit and double-hits contact explosion damage models are estab-lished in this paper to simulate the damaging mechanism of cabins under actual weapon hits. In this model, the first hit location is artificially specified, while the second hit location is longitudinally and vertically distributed along the profile. Next, the various response surfaces of flooding condition with different second hit locations are calculated. Finally, a survival probability mathematic model is pre-sented to give a quantitative index for the damaged ship, which shows promising results that satisfy cer-tain calibration specification and the deterioration of ocean waves. In brief, the proposed method is ap-plicable for assessing the vulnerability and survivability of aircraft carriers.
