舰船战损评估分析方法研究

对舰船战损分析方法进行系统的分析与建模,对不同武器的炸点分布进行模拟,分析在接触爆炸和非接触爆炸作用下舰船主要设备的破坏模式,分析在爆炸火球、破片和冲击波超压破坏下设备损伤的计算模型,建立设备的冲击响应模型,提出设备的破坏判据,给出爆炸作用下舰船生命力评估的计算机仿真计算方法,并通过数学建摸和模拟分析对系统在破坏环境下的损伤概率进行分析,运用模糊评估法计算系统的生命力指标。计算结果表明,该方法可直观地分析出生命力设计较弱的环节。

Study on the Analysis Method for Battle Damage Assessment of Ships

The analysis method for battle damage of ship was analyzed and modeled.The explosive point distribution of each kind of weapon on ships was simulated.The damage modes for main equipment of ships were analyzed under contact explosion and non-contact explosion.The equipment damage calculation models under fireball,explosion fragment and shock wave overpressure were respectively established.The impact response model of equipment was established.A numerical simulation method for evaluating the survivability of ships was given.By using mathematical modeling and simulation analysis,the damage probability of ship system was calculated.The survivability index was calculated with fuzzy evaluation method.The results indicate that the method can directly work out the weakness of ships in survivability design.
