TL;DR: In this paper, the authors examined the vibration characteristics and vibration control of complex ship structures and found that the input mobilities of a ship structure at engine supports, due to out-of-plane force or bending moment excitations, are governed by the flexural stiffness of the engine supports.

TL;DR: In this paper, the motion equations for the nonlinearly connected floating bridge, considering the nonlinear properties of connectors and vehicles' inertia effects, are proposed, and the super-element method is used to condense the whole calculation scale and the direct integration and Newton-Raphson iteration method are applied to solve the reduced equations.

TL;DR: In this paper, the natural frequencies and mode shapes, and the coupled rigid-body (rolling) motion and elastic (flexural and torsional) vibration of a partial-catenary-moored floating bridge subjected to a moving load are investigated.
