| Abstract: | The dynamic response process of the cabin model under non-contact underwater explosions is computed with ABAQUS, which is the non-linear finite element software. The time history of acceleration of each position is presented, and the preciseness of simulation is confirmed with actual results of model explosion tests. In the end, the influence of the cabin under non-contact underwater explosions is studied. The study is worthwhile to the anti-shock property evaluate of ship structure. |
