中文摘要：

为了研究离散多层爆炸容器筒体的抗爆性能和尺寸效应,对材料相同、几何相似、放大系数为4的2种离散多层试验圆筒进行了中心爆炸加载试验。试验结果表明,2种离散多层圆筒极限承载TNT装药的相对质量为0.89%～1.11%,尺寸放大4倍后离散多层圆筒的抗爆性能没有明显的降低。根据能量相关理论分析认为,由于2种圆筒中钢带特征尺寸保持不变,作为离散多层爆炸容器筒体承载主体的钢带层不存在强烈的能量尺寸效应,从而使得离散多层爆炸容器筒体整体抗爆性能未被显著削弱。

英文摘要：

Nine discrete multi-layered cylinders were manufactured with the same materials and the magnification factor of 4. A series of explosion experiments were conducted under internal explosive loading to investigate their anti-explosion capability and scale effect. Experimental results show that their limiting TNT charges are all 0.89%~1.11% in relative mass, and that the anti-explosion capability of the discrete multi-layered cylinders is not attenuated significantly after magnified 4 times. It is attributed to the reason that there is no strong scale effect of an energy nature in their steel ribbon layers which construct the main load-supporting capability of discrete multi-layered explosion containment vessels.
