On the Parametric Rolling of Container Vessels
Brodogradnja : An International Journal of Naval Architecture and Ocean Engineering for Research and Development, 2010 The main objective of this article is to outline a simple method to identify whether a ship is susceptible to extreme rolling, in order to avoid or to reduce the effects of that phenomenon. A short review of the current classifi cation societies’ recommendations is given, as well as a brief description of the physical phenomenon of parametric roll ...

Parametric Rolling at Main Resonance
Brodogradnja : An International Journal of Naval Architecture and Ocean Engineering for Research and Development, 2008 The parametric resonance of the induced rolling is a typical dangerous situation for the transversal stability of ships operating in longitudinal waves. This paper presents the results of experimental tests regarding the seakeeping performances of a 2700 dwt cargo model at full loading, in regular longitudinal waves.

Numerical calculation and mechanical mechanism analysis of ship parametric rolling
Zhongguo Jianchuan Yanjiu, 2020 [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 ...

Parametric roll oscillations of a hydrodynamic Chaplygin sleigh
Nonlinear Dynamics, 2023 Biomimetic underwater robots use lateral periodic oscillatory motion to propel forward, which is seen in most fishes known as body caudal fin (BCF) propulsion. The lateral oscillatory motion makes slender-bodied fish-like robots roll unstable. Unlike the case of human-engineered aquatic robots, many species of fish can stabilize their roll motion to ...
