Abstract : The response of hull mounted submarine equipment structures can be idealized as an N-mass system and the hull as a rigid circular cylinder. Motion of the cylinder is derermined by reflection of a one-dimensional pressure wave from the cylinder. Cavitation at the hull-water interface is included in the analytical model. Results of this study are compared to those obtained using a flat plate representation of the hull. Because of the hull curvature in this improved model, the rise time of the equipment much less than in the previous model. As a result, agreement with trends observed in the experimental data are improved. (Author)
