Prevention of parametric rolling through multi-objective optimisation [PDF]
, 2015 IMO is developing new intact stability criteria which include parametric rolling and they will have an impact on some ship types. A benchmark study of those criteria on C11 containership is presented herein. Moreover, the authors use them as an objective

Numerical Study of Parametric Roll on a Fishing Vessel [PDF]
Volume 9: Odd M. Faltinsen Honoring Symposium on Marine Hydrodynamics, 2013 Present research activity examines numerically the occurrence of parametric roll on a fishing vessel interacting with regular head-sea waves. The adopted solver is an efficient 3-D numerical Domain-Decomposition strategy for the seakeeping of a 6-dof vessel without and with small forward speed and possibly subjected to bottom-slamming and water-on-deck

Multi-parametric Dynamic Analysis of a Rolling Bearings System
Strojniški vestnik – Journal of Mechanical Engineering, 2021 A method for calculating amplitudes and constructing frequency characteristics of forced and self-excited vibrations of a rotor-fluid-foundation system on rolling bearings with a non-linear characteristic based on the method of complex amplitudes and harmonic balance has been developed.

Rolling bearing parametric excitation of a jeffcott rotor system
, 2020 Rolling bearings are still widely used in aeroengines. Whenever rotors are modeled, rolling bearing components are typically modeled using springs. In simpler models, this spring is considered to have a constant mean value.
