水下爆炸对比格犬损伤试验研究

为研究水下爆炸下水中作战人员的损伤模式和阈值，作者使用试验专用比格犬作为人体替代物，分别开展了克级、千克级TNT水下爆炸试验，直接观察到比格犬在水下爆炸冲击波与气泡脉动作用下的全过程响应，试验结果表明：水下爆炸作用下，含气器官如肺、听器等，遭遇冲击波、气泡、负压等载荷的作用，损伤最为严重，且无论头部是否露出水面，脑部都会产生一定程度的损伤；在同等水下爆炸条件下，潜泳战位比格犬的损伤半径约为泅渡战位的2.5倍；获取了泅渡与潜泳战位比格犬在水下爆炸下的损伤模式和阈值，可为人员水下爆炸冲击伤预测和救治提供参考。

Experimental Investigation of Underwater Blast Injuries to Beagles

To study the underwater blast injury modes and thresholds for human, beagle dogs are adopted for gram-and kilogram-level underwater blast tests. The response of beagles to shock wave and bubble pulsation loadings is observed. Air containing organs such as lung and auditory apparatus suffer the most from the shock wave, bubble pulsation, negative pressure and other loads. Whether the head is above the water or not, the brain will be injured to some extent. Under the same underwater blast loading, the damage radius for a beagle in diving position is approximately 2.5 times that of one in swimming position. From experiments, the injury modes and thresholds for beagles under underwater blast are concluded, which can be used to predict and treat underwater shock injuries.
