Abstract

Experiment of cabin model subjected to close-in underwater explosion from bottom attacting was investigated to explore the damage failure model of warship, The demolishing region datas of cabin model together with shock environment information were obtained. Furthermore, by contrasting the experimental results from the case of close-in underwater explosion from ship broadside attacting and far-mild field shock environment trial. It is concluded that: (1) the typical failure of cabin model mainly contains the whole deformation, tearing in the middle along with local dish on both sides; (2) the bottom attacting method has more destruction ability in contrast to the ship broadside attacting way, it is found more than 40% damage effect can be increased according to the experimental results; (3) the variation tendency of measuring point shock spectra between close-in and far-mild field bottom underwater explosion at middle and high frequency level, Unfortunately, for the low frequency level the values of close-in underwater explosion are greater than the latter.
