Abstract
The paper investigates stochastic dynamics and stability of a ship-based crane. The simplified nonlinear model of the payload motion is considered, where the excitation of a suspension point is imposed due to heaving motion of waves. The latter enters the system parametrically, leading to a Mathieu type nonlinear equation. Two models are considered: A single-degree-of-freedom system and two-degree-of-freedom system coupled through a nonlinearity and parametric excitation. Both systems analyzed analytically using approximate methods and numerically. The stability boundaries are calculated for both cases, using the Lyapunov exponent.
