Experimental Study on Damage Effect of Simulated Ship Cabin Subjected to Missile Dynamic Explosion
-
摘要: 设计了基于火箭橇的导弹动爆试验,介绍了模拟船舱的结构尺寸、测试点的布设情况及测试仪器性能。通过获取的断线、光、压力、加速度信号得出如下结论:测试方法有效;冲击波在舱室内传播不均匀,导弹运动方向反射冲击波很大,反方向较小,两者比例可达3.5∶1,舱室的角隅部位冲击波压力高于壁面正反射压力;导弹穿甲时舱壁的冲击振动高达10 000 g,且穿甲舱壁的冲击远大于其它舱壁,被破片击中会加大舱壁的振动幅值。Abstract: An experiment of missile dynamic explosion carried by rocket sled was performed. The structure size of simulated cabin, layout of testing points and properties of used instruments were introduced. According to broken lines, acquired light, pressure and acceleration signals, three conclusions were made as follows: First, the designed testing method is effective; Second, the transmission of shock wave in cabin is uneven, while the reflection shock wave on the missile moving direction is about 3.5 times of the other side; The shock wave pressure on the cube corner of cabin is higher than normal reflection pressure on the wall; Finally, the impact vibration on the penetrating bulkhead is about 10 000 g, which is much higher than other points; The vibration amplitude of bulkhead will increases as hit by shell fragments.
