摘要
基于薄壁壳理论和水下爆炸理论,对圆柱形水下爆炸实验容器在爆炸冲击波作用下弹性范围内的壁部应变进行了理论分析和实验研究。导出了圆柱形水下爆炸实验容器在爆炸冲击波作用下壁部弹性应变与容器直径、壁厚及内部爆炸药量之间的关系,并对计算结果进行了实验验证。实验表明,公式求解结果与实验结果具有较好的一致性。
The elastic shell strain of the cylindrical vessel produced by the inner underwater explosion shock wave was analyzed and evaluated, according to the thin shell and underwater explosion theory. The relationship between the elastic shell strain and three main factors, i. e. the vessel diameter, the shell thickness and the mass of the inner explosion, is revealed by numerical simulation, and is examined by detailed experiments. The experimental results show a better consistency with the numerical results.
