爆破型鱼雷爆炸威力试验评估方法

Test Estimating Methods for Torpedo Blasting Warhead Explosion Power

为了探寻评估爆破型鱼雷战斗部爆炸威力的科学方法,研究了爆破型鱼雷的两种毁伤模式,梳理了在工程设计时采用的鱼雷爆炸威力表征模型,提出用能量法、通过试验测量手段,来评估战斗部爆炸威力,并建立评估模型。结果表明:爆破型鱼雷对水面舰艇的毁伤模式分接触爆炸和非接触爆炸;接触爆炸对舰船壳体局部结构造成毁伤,非接触爆炸对船底局部结构和总纵强度造成破坏;工程设计上采用的鱼雷爆炸威力表征模型,不适用于采用新型防护设计的现代舰船,忽视了气泡能对舰船总纵强度的破坏作用;用能量法评估爆破型鱼雷爆炸威力科学可行;鱼雷无靶静爆、实航固定靶、实航活动靶3种试验模式,不仅可实现威力评估,结合靶船毁伤情况,还可以对鱼雷的毁伤能力作出评价。

The study of damage m timating method and test methods ode for blasting torpedo warhead,explosion power models, the energy eswas presented in this paper. Resuhs show the following characters： The damage mode of blasting torpedo on surface ship includes contact explosion and noncontact explosion, and the former causes the local structure damage of outer hull, while the latter causes the local structure damage of bottom and longitudinal strength; Torpedo explosion power characterization model is adopted in warhead engineering design, and does not apply to the use of modem ship, and bubble effects on the longitudinal strength is ignored; By the method of energy These three kinds of test methods can realize not ability evaluation evaluation of blasting torpedo explosion power is feasible ; only the explosion power evaluation, but also the damage
