摘  要:选取3种比例尺寸的战斗部,通过建立有效的有限元模型,利用ALE方法分析研究无限水域中壳体对不同尺寸爆破型战斗部爆炸威力的影响。结果表明,壳体对爆炸威力的影响呈现振荡特性,爆距越大振荡越大;壳体厚度与装药尺寸满足一定关系时将增大爆炸威力;但壳体厚度相对于装药尺寸较小时爆炸威力小。可为水中兵器爆炸威力设计与评估提供参考。Based on evaluation method of warheads of underwater explosion,three blasting warheads were chosen to be studied.First,the effective finite element model was made Then,the ALE method was used to study effects of shell on lethality of different proportional size blasting warheads in infinite field.It can be resulted that the effects showed characteristics of oscillation and attenuation.The faster the explosion,the greater the attenuation.When the shell thickness related to the explosive size satisfies certain condition,the lethality will increase.But if the shell thickness is much less than the explosive size,the lethality will decrease.The research can provide reference for the lethality design and assessment of underwater weapon.
