摘要:
为了更好地保护小当量爆炸物处理人员的安全,提出了一种由胶体、聚氨酯、泡沫铝和凯夫拉4种材料构成的圆柱形复合防护结构。对100 g TNT爆炸物选择模型比例为1：1,利用AUTODYN软件建立二维仿真模型,采用2D-Euler算法数值模拟此防护结构对爆炸冲击波的减弱效果，并进行分析研究。研究得出:复合防护结构能很好地降低冲击波超压峰值，从而间接地增强人体对超压的忍受度,保证一定范围内人员的生命安全。该防护结构具有便携性、机动性及对爆炸冲击波的高效衰减性,正好适用于轻量、便携及有效防护的应用背景,对相关防护结构的研究设计起到很好的参考作用。
Abstract:
In order to guarantee the safety of personnel handling small quantities of explosives, a cylindrical composite protective structure made of four materials, including colloid, polyurethane, aluminum foam and Kevlar was proposed. A 1：1 ratio of 100 g TNT explosives was selected. A two-dimensional simulation model was developed by AUTODYN software. The attenuation effect of this structure on the blast shock wave was numerically simulated by 2D-Euler algorithm and analyzed. The study shows that the compound protective structure can well reduce the peak value of shock wave overpressure, thereby indirectly increasing the tolerance of human exposure to overpressure and ensuring the life safety of personnel within a certain range. The protective structure has portability, mobility and high efficiency decay of blast shock wave, which is suitable for the application background of light weight, portable and effective protection and plays a good reference role for the research and design of the relevant protective device.
