nonlinear ship rollingIn this paper, the probability density function (PDF) and the mean up-crossing rate of nonlinear ship rolling in random beam seas are investigated. The excitation of stationary random sea waves is approximated as a second-order linear filtered white noise. The Fokker–Planck...
gyrostabiliser, gyrostabilizer - a stabilizer consisting of a heavy gyroscope that spins on a vertical axis; reduces side-to-side rolling of a ship or plane helm - steering mechanism for a vessel; a mechanical device by which a vessel is steered hospital ship - a ship built to serve as ...

Safety analysis of ship rolling in rough sea Non-linear ship rolling and capsizing in irregular waves is analysed by a single degree-of-freedom system. The random wave excitation depends on sea state,... Ivo Senjanović,Joško Parunov,Goran Ciprić - 《Chaos Solitons & Fractals》 被引量...
14.The safe basin and capsizing route of nonlinear random motion of the ship in the high seas are investigated in this paper.研讨了随机海浪中船舶非线性随机横摇运动倾覆过程和安全域问题。 15.Nonlinear Rolling and Capsizing of Ships in Rough Sea随机海况下的非线性船舶横摇和倾覆 ...
A 1-DOF mathematical rolling model was used instead of expensive and time consuming towing tank tests for the training of the ANN. On-board safety assessments can significantly enhance operational guidance to the crew also in critical conditions. From the viewpoint of damage stability, the ...

Objective The parametric rolling is a special instability phenomenon of ship in the wave. The current research proves that the change of the stability parameter when the wave passes through the hull is the reason for the rolling motion of the hull, but the mechanical mechanism is unclear. Method...
