Abstract

Abstract

Based on the velocity distribution of fragments of a metal hemispherical shell subjected to explosive loading, a new fragment recovery system with the combination of polyurethane, water and polyurethane medium was designed. The applied waterproof polyurethane foam barrel is made up of three symmetric components each with sidewall and bottom formed in a mold. The foam barrel is filled with water at the bottom, and an additional floating foam board with a certain thickness is applied in order to protect the outer recovery tank from the impact of fragments. The full recovery experiment with the foam barrel was carried out for a 45 steel hemispherical shell under central point explosion. The results showed that more than 88% fragments, which penetrated through the sidewall of the foam barrel and the floating foam board, could be directly recovered from the bottom of the recovery tank. The fragments have well discernible inner and outer surfaces. The floating board and water would effectively reduce the speed of formed fragments, and the bottom of the foam barrel remained undamaged. The newly designed recovery system can recover flying fragments close to 2π solid angles, thus is suitable for a large range of recovery experiments in which experiment device is on one side of the initiation point. This indicates the appearance type of experiment devices is extended. Besides, the new system reduces the total size of the combined attenuation layer to 70 cm in the vertical direction, thus providing a basis for further optimizing and reducing the size of the recovery tank. The characteristic distribution of the fragment, including mass, thickness and size, et al., was analyzed based on the recovery technique. The difference of characteristic between hemispherical shell fragments and cylindrical shell fragments was also analyzed briefly. Results show that the fracture strain of hemispherical shell is obviously less than that of cylindrical shell. This research provides useful experimental data supporting the study of fracture mechanism of expanding shells under different stress states.
