| 摘 要： | 分析内爆炸圆管膨胀破碎过程的应力,提出确定内爆炸圆管断裂半径的复合判据,从理论上预测不同材料圆管的破片初速度.采用GSJ高速摄影记录仪测试不同材料圆管的破片初速度,并与理论预测值行比较.结果表明,采用复合判据得到的理论预测结果与实验测量结果能够较好吻合.

| Abstract: | Stresses of the in-explosive cylinder were analyzed,compound criteria for determinating the fracture radius was put forward to calculate the initial velocity of cylinder fragment.High speed photography was adopted to test initial velocity of cylinder fragment of several kinds of materials.The theoretic calculated value of initial velocity was compared with the test value.The result indicated that,for the same kind of material,the theoretic calculated initial velocity value,which adopted compound criteria,matched to test value well. |
