Conclusions <strong>of</strong> forced motion experiments(con’t.)Added mass <strong>and</strong> damping matrices, A <strong>and</strong> B. Forlow to moderate planing <strong>speed</strong>s, Cv=1.5 - 2.5, theadded mass coefficient, <strong>and</strong> to a lesser extent thedamping coefficient, can be frequency dependent.When the experimental results were analyzed using aconstant restoring force matrix, the added mass <strong>and</strong>damping in heave, Aj3 <strong>and</strong> Bj3, j=3,5 showedrelatively little amplitude dependency compared tothe added mass <strong>and</strong> damping in pitch, Aj5 <strong>and</strong> Bj5,j=3,5.<strong>Armin</strong> <strong>Troesch</strong>University <strong>of</strong> MichiganDepartment <strong>of</strong> Naval Architecture <strong>and</strong> Marine Engineering<strong>Dynamics</strong> <strong>and</strong> Hydrodynamics <strong>of</strong> High Speed CraftJune 29, 2010Barranquilla, Colombia
