The analysis on shock design spectrum of shipboard equipments

Dynamic design analysis method (DDAM) is not related tightly with the condition of non contact underwater explosion(undex). The shipboard shock environment of non contact underwater explosion has got through numerical simulation with Abaqus program. The design spectrum to different mass of shipboard equipments for different case of undex was got through integrating response spectrum of deck and the double degree dynamic model of deck and plus-minus triangular wave load of BV043/85. The design spectrum has right law and rational value.
