Basing on the detonation theory, the structure of the deformable warhead was simplified to be double layer cylindrical shells under the detonation. Plastic hinges were introduced into the loading section of the shell, which contacted with the deforming charge, and the deforming charge was divided into small segments accordingly. Loading and movement of these segments were analyzed. Deforming shape of the cylindrical shell under the loading with equal distribution was bulgy, and the displacement of shell segments was obtained. Deforming charge with different thickness, according to the displacement of the segment, was set up to realize the same displacement of the shell segments on the loading direction. The D-shape was achieved theoretically, and the shape of deforming charge was designed accordingly. Numerical simulation validated the feasibility of the designed plan. The results indicate that the deformable warhead with the new-designed deforming charge can realize the D-shape.

基于炸药瞬时爆轰理论,将战斗部变形阶段的结构简化为辅助装药,对等效圆柱壳体实施爆轰加载,并在等效壳体上的加载段引入若干个塑性铰,相应地将辅助装药划分成与塑性铰相对应的若干个独立微元。针对均匀加载下等效壳体的原始位移分布,采用具有能量分布梯度的辅助装药加载进行匹配,设计出能实现D型型面的辅助装药形状,最后通过数值模拟进行验证。结果表明,采用该形状的辅助装药能实现较理想的D型弹体变形型面。

基于炸药瞬时爆轰理论,将战斗部变形阶段的结构简化为辅助装药,对等效圆柱壳体实施爆轰加载,并在等效壳体上的加载段引入若干个塑性铰,相应地将辅助装药划分成与塑性铰相对应的若干个独立微元。针对均匀加载下等效壳体的原始位移分布,采用具有能量分布梯度的辅助装药加载进行匹配,设计出能实现D型型面的辅助装药形状,最后通过数值模拟进行验证。结果表明,采用该形状的辅助装药能实现较理想的D型弹体变形型面。

Basing on the detonation theory, the structure of the deformable warhead was simplified to be double layer cylindrical shells under the detonation. Plastic hinges were introduced into the loading section of the shell, which contacted with the deforming charge, and the deforming charge was divided into small segments accordingly. Loading and movement of these segments were analyzed. Deforming shape of the cylindrical shell under the loading with equal distribution was bulgy, and the displacement of shell segments was obtained. Deforming charge with different thickness, according to the displacement of the segment, was set up to realize the same displacement of the shell segments on the loading direction. The D-shape was achieved theoretically, and the shape of deforming charge was designed accordingly. Numerical simulation validated the feasibility of the designed plan. The results indicate that the deformable warhead with the new-designed deforming charge can realize the D-shape.
