The Effect of Shallow Water on Roll Damping and Rolling Period
… effort has been made to quantify and predict roll damping of vessels in the past. Similarly, efforts have been made to provide effective methods for calculating the roll gyradius of vessels. Both the damping and the gyradius of a vessel are traditionally quantified through the use of a sally …

A Study on the Feasibility of Using Fractional Differential Equations for Roll Damping Models
… with an eye toward modeling different forms of roll damping. Relations between the order of differentiation a and damping coefficient b in the FDEs have been drawn for changing damping, added moment of inertia, and initial roll angle. A pitch model has also been studied and compared to the roll …

Analysis and Modeling of Hydrodynamic Components for Ship Roll Motion in Heavy Weather
Ship roll motion has been the subject of many studies, because of the complexities associated with this mode of ship motion, and its impact on operability, safety, and survivability. Estimation and prediction of the energy transfer and dissipation of the hydrodynamic components, added inertia and …

Experimental Evaluation and Adams Simulation of the Kinetic Suspension System
… stability, and ride by passively decoupling roll stiffness from articulation stiffness and roll damping frombounce damping.The first stage in the process involved full-scale vehicle rollover testing of a standard and Kinetic equipped Honda CR-V using the NHTSA roll rate feedback fishhook …

Full Scale Investigation of Bilge Keel Effectiveness at Forward Speed
… predict heave, pitch, sway, yaw and even surge, roll motions are much more difficult. Roll is the one motion that is very dependent upon viscous effects of the fluid. Recently, at David Taylor Model Basin, there have been model experiments where the bilge keels were instrumented in order to …
