Study on Damage Capabilities of Multiple Hulls Structure under Underwater Explosion

Abstract:

In order to study the damage capabilities of multiple hulls structure under underwater explosion, the damage mechanism of contact blasting and noncontact blasting on target is analyzed, and the formula of shock wave in water goes through multiple hulls structure is put forward. Using armor plate and aluminum plate、copper plate、rubber plate as models respectively, numerical simulation is done by LS-DYNA, the stress distribution and displacement of multiple hulls structure under underwater contact blasting are got. Lastly, test research on damage capabilities of multiple hulls structure under underwater explosion is finished. The result shows that the anti-explosion capabilities of multiple hulls will improve greatly when underwater ship adopted this kind of structure.
