NUMERICAL ANALYSIS BY DIGITAL COMPUTER PROGRAM ROSAS ON RESPONSES OF SHIP HULL STRUCTURE AT SEA

Numerical analyses made with the digital computer program ROSAS on responses of a ship-hull structure at sea were developed at the David W. Taylor Naval Ship Research and Development Center. The program simulates the hull girder structural response of a ship, including dynamic effects when it encounters head or following seas of the regular, irregular, discrete, standing, or other wave forms. Response calculations include rigid and elastic body motion, bending moment, and shear. Vibratory hull girder modes can also be determined, and the effects of bow flare, bottom slamming and springing can be included. Computations have been compared with actual ship responses. Results are in good agreement with those obtained from actual ship sea trials, model experiments, a computer program developed by the Ship Structure Committee, and an earlier analogue computer program developed by the Centre.
