Experimental Study on Damage Effect of Simulated Ship Cabin Subjected to Missile Dynamic Explosion

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.
