摘要:
为了实现聚能战斗部对水下目标的高效毁伤,在传统聚能战斗部的基础上设计了一种采用不同材料的球缺罩与偏心亚半球形罩组合的聚能战斗部。阐述了复合材质组合式聚能战斗部的结构设计及作用原理,利用有限元软件AUTODYN数值模拟了其成型及侵彻水下靶板的过程,并与传统的偏心亚半球缺式和单一材质组合式战斗部的毁伤效果进行了对比。研究表明,复合材质组合式战斗部形成的前级杆式射流侵彻水介质过程中可以为后级杆式射流开辟无耗能通道;在相同炸高下,侵彻相同厚度的水介质与靶板后,与传统杆式射流相比,复合材质杆式射流的动能衰减率最小,剩余动能提升了28.59%。该复合材质组合式聚能战斗部可以实现对水下目标的高效毁伤。
Abstract:
In order to achieve efficient destruction of shaped warheads to underwater targets, a composite-material warhead with an eccentric sub-hemispherical liner and spherical liner was modified from the traditional shaped warhead. Structural design and function principle of the combined shaped warhead were introduced. Processes of forming and penetrating the underwater target were simulated by AUTODYN. Damage effects of traditional eccentric sub-hemispherical warheads and single-material combined warhead were compared with the composite-material warhead. The results show that the forward jet formed by composite-material warhead can provide the moving space for the backward jet in the process of penetrating the water medium. Under the same burst height, after penetrating the water medium and the target plate of the same thickness, the residual kinetic energy of composite rod-like jet is 28.59% higher than that of traditional rod-like jet. The designed composite-material shaped charge warhead can effectively damage underwater targets.
