Roll Angle of a Ship: Simple Equation Explained
Reply to thread
Message
[QUOTE="SteamKing, post: 5505239, member: 301881"] The rolling motion of a ship is generally a non-linear phenomenon. For small angles, the rolling motion may be linearized approximately so that it corresponds roughly to simple harmonic motion, like what a pendulum experiences when it is disturbed from the equilibrium position. I don't know where you obtained the equation in your post, but A is generally not the amplitude of the incident wave. What this equation is telling you is that the roll angle of the vessel is periodic in time, with a certain amplitude of roll, frequency, and phase w.r.t. some other datum. [/QUOTE]
