A theoretical model for the evaluation of protective capability of a sandwich bulkhead structure in the close range of warhead explosion
-
摘要: 为改善当前战斗部近距爆炸下基于单纯抗爆或抗穿甲载荷开展防护结构设计的不足，本文中建立了战斗部近距爆炸下夹芯复合舱壁结构防护能力的理论评估模型，提出了联合作用下夹芯复合舱壁结构的防护能力需同时满足抗弹性能和整体变形破坏两方面要求。具体步骤为：首先计算战斗部爆炸后的联合毁伤载荷，然后基于抗弹理论模型评估夹芯复合舱壁结构的抗弹性能。若满足要求，则进一步根据联合作用理论模型校核夹芯复合舱壁结构在冲击波和破片群联合作用下是否满足整体变形破坏要求，判据为后面板是否产生撕裂、破口破坏。与有关实验结果进行了计算比较，结果吻合良好，证明了此理论评估模型的合理性。Abstract: In order to make up for the shortcomings in protective structure design based on simple anti-blast or anti-armor load, a theoretical model was proposed for evaluating the protective capability of sandwich bulkhead in the close range of a warhead explosion, and its protection capability should meet the requirements of both the ballistic performance and the overall deformation and destruction. The first step is to calculate the combined damage load under warhead explosion. Then, based on the ballistic theory model, it can be used to evaluate whether the composite structure meets the requirements of the ballistic resistance. If it is satisfied, the requirements of composite sandwich bulkhead on overall deformation and failure under the combined load of shock wave and fragment group are further checked according to the combined damage theory model, and the criterion is whether the rear panel is broken or being torn. The experimental results are in good agreement with those of the domestic experimental results, which shows that the theoretical evaluation model is reasonable.
