摘要(Abstract)：
为探讨在不同水深、海底底质、药量条件下的海底爆炸载荷所引起的冲击响应的变化规律,设计了2kg和6kg TNT球形装药在不同深度海域和不同海底底质条件下的海底爆炸试验,测量了不同距离和方位上圆柱体受到的冲击响应,包括压力时程曲线和三轴加速度时程曲线。结果表明:加速度曲线与压力曲线在时间上有一致的对应关系;时程曲线上滞后流出现时间随药量增大而延后;试验条件下,圆柱体加速度响应垂向最大,横向次之,纵向最小;圆柱体冲击响应主要来自于冲击波。
In order to study the variation of shock response caused by submarine explosion in different water depth,seabed,charge weight conditions,the blasting tests with 2kg and 6kg TNT spherical charge had been designed in different depths and seabed conditions.Different distance and azimuth cylinder impact response had been measured,including pressure time history curve and three axis acceleration time curve. The results showed that the acceleration curve corresponded to pressure curve in time,appearance time of lagging flow in time history curves delayed with charge weight increasing,vertical acceleration of cylinder was the maximum,then lateral and longitudinal was the minimum,and load cylinder shock response was mainly from the shock wave.
