COMPUTER SOLUTION OF ACCELERATIONS CAUSED BY COLLISION. VOLUME I. REPORT
Using methods of forced vibration analysis, calculations of impact accelerations were carried out in way of the reactor space of a 600,000 ton nuclear tanker when struck by another ship in the area of the collision barrier. The General Bending Response Program was used by representing the ship as an elastically coupled non-uniform beam-spring model subject to a Fourier series representation of the transient force of impact. Sectional properties were developed for the ship in both ballast and full load conditions in order to describe the model. Sensitivity calculations were made for variations in loading conditions, ship-hull damping, impact duration and impact magnitude for the lateral mode of vibration. An additional calculation was made for the combined torsional-horizontal bending mode of vibration.
