Abstract:

A significant number of unexploded bombs have remained on the battlefield since World War II. To handle these unexploded bombs effectively and efficiently, it is crucial to provide a robust protection and lightweight explosion-proof shelter that ensures the safety of bomb disposal experts. In this study, three materials were selected: aluminum alloy 6061-T6, ultra-high molecular weight polyethylene (UHMWPE) fiber laminates and carbon fiber laminates. The deformation resistance and shock wave overpressure attenuation effects of curved and square explosion-proof shelters under the action of shock wave are compared through real explosion experiment and finite element simulation. The test results indicate that, for target plate with equal surface density, the carbon fiber laminates exhibit superior deformation resistance compared to UHMWPE fiber laminates and aluminum plates. Furthermore, the simulated results demonstrate that the curved structures offer better deformation resistance than square structures. Finally, when the curved explosion-proof shelter is subjected to an explosive impact at a distance of 3 m from a 2 kg TNT charge at a height of 0. 5 m, it generates lower transmission overpressure than the square counterpart due to its enhanced deformation resistance. In the case of minimal deformation observed in this scenario, the overpressure within the shelter remains below 20 kPa—ensuring personnel safety without any injuries incurred. Material selection has minimal influence on the clipping effect of curved explosion-proof shelter, however, the carbon fiber laminates yield the optimal explosion-proof effect for square explosion-proof shelters. © 2023 China Ordnance Society.
