Abstract:

A feasibility study is described in which springing bending moment response of a 1000-ft. ore ship model was measured. Regular waves of length between 6 and 14 inches were generated to excite the 1144-scale model hinged at midships over a range of foreard speeds between 1.0 and 4.5 ft.sec. significant springing was obtained under resonant conditions which corresponded to 39.6 and 19.5 rad.sec., respectively, for each of the connecting beams used. Analytical solution of the model springing phenomenon is also given using Goodmans theory, and correlation between experimental and theoretical results is shown to be encouraging.
