Abstract Explosion test of 30kg Semi-armor-piercing warhead in the combined cabin of warship is completed. In the test, Upper and lower cabins are completely disintegrated. Cabins are broken in the weld zone. Maximum overpressure of lower cabin is 6.5 MPa and that of upper cabin is 0.6 MPa. By using numerical simulation method, influence of missile hole position and explosive charge velocity on damage effect is analyzed. Results show that difference of hole position will affect superposition of detonation products in cabin, thus changing position where the first structural fracture occurs in the cabin, leading to difference of damage. Increasing velocity of charge will make damage of positive direction bulkhead more serious, but damage degree of negative direction will be reduced. When velocity of charge exceeds 2 Ma, detonation products will not be able to affect cabin in negative direction of velocity.
