| Abstract: | Parametric resonance can lead to dangerously large rolling motions, endangering the ship, cargo and crew. The QR-factorization method for calculating (LCEs) Lyapunov Characteristic Exponents was introduced; parametric resonance stability
of ships in longitudinal waves was then analyzed using LCEs. Then the safe and unsafe regions of target ships were then identified.
The results showed that this method can be used to analyze ship stability and to accurately identify safe and unsafe operating
conditions for a ship in longitudinal waves. |
