    摘要:

    汽车爆炸在涉爆案事件中越来越常见. 为有效打击国内外恐怖分子,支持汽车爆炸案预防、刑侦与破案工作,本文针对轿车车型进行了爆炸毁伤特征的现场实验研究. 实验分别在汽车底部中心,后备箱中心,驾驶座下引爆炸药. 爆炸过程中两个高速摄影通道记录爆炸毁伤动态过程,同时利用冲击波超压测试系统分析外场不同方向的超压分布规律,并进行了车身壁面压力测试. 实验获得大量汽车爆炸毁伤图像及碎片落点数据,得到较为准确的超压分布数据和部分车身壁面超压状态. 本研究获得了不同炸点位置对汽车爆炸毁伤的影响,以及超压分布等信息,可有效支撑汽车爆炸案事件的现场还原和侦破工作.

    Abstract:

    Vehicle explosion is becoming more and more common in explosion-related incidents. In order to combat domestic and foreign terrorists, and to support the criminal investigation and prevention about vehicle explosions, experimental research on the damage features of car under blast loading has been performed in this paper. In our experiments, explosives were detonated in the center of the bottom of the car, backup box center and under the driver’s seat respectively. The dynamic process of experiments was recorded by two high-speed photographic channels. Free field overpressure distributions in different directions were analyzed by using the shock wave overpressure test system, and the overpressure on the car body was obtained as well. A large number of automobile damage images and debris distribution data were achieved by camera. The effects of different explosion positions on blast damage features as well as the overpressure distribution of vehicles were obtained in the experiments, which are of significance to the scene restoration and detection of car explosion cases.
