EFFECTS OF NON-LINEARITIES ON HULL SPRINGING
Nonlinear and linear aspects of ship springing were examined. Experimental values for the hydrodynamic forces were used to estimate the influence of nonlinear excitation on the total springing bending moment. Based upon the examples given, conclusions were presented regarding: dependence of springing response on the vessel's natural frequency and speed; excessive stresses produced by a relatively small sea state; and effects of springing excitation on the overall bending stresses.
