摘要: 由于水中兵器战斗部采用不同的定向起爆方式时将产生不同的爆炸威力场，为了寻求一种能获得较大定向能量增益以及较大定向能量增益区域的定向起爆方式，文中通过仿真软件AUTODYN建立了水中兵器战斗部采用几种典型的定向起爆方式时在水中爆炸的仿真模型，并对其不同定向起爆方式下的爆炸威力场参数进行了仿真计算与对比分析，得出了不同定向起爆方式与爆炸威力场的对应关系，并结合理论分析与工程实际应用，提出了一种切实可行且相对较优的定向起爆方案。Abstract: An underwater warhead with different directional detonation modes will produce different explode power field. In order to seek for a directional detonation mode which can achieve more directional energy gain and larger area of the gain, simulation models of an underwater explode warhead with different directional detonation modes are established with the simulation software AUTODYN, and the parameters of explode power field are calculated and comparatively analyzed. Then the relationship between directional detonation mode and explode power field of underwater warhead is obtained. According to the theoretic analysis and the practical use, a feasible and more excellent directional detonation mode is presented finally.
