Research on Ship's Dynamic Response and Equipment's Shock Environment under Explosion in Shallow Water

The dynamic response of the warship as well as the shock environment of the equipment under the explosion in shallow water are investigated by means of the software MSC/Dytran.Based on the research on the shock wave caused by the explosion in shallow water with four kinds of water bottom,the ship's dynamic response to the explosion with a rigid bottom is simulated.The shock environment of the ship's engine room is analyzed by using the acceleration response of the ship structure.Some laws of the influence of the reflected bottom wave are summarized with the comparison of the ship's response and the equipment's shock environment under the explosion in infinite water.
