NONLINEAR COUPLING RESPONSES OF THE PLATFORM ROLLING AND PITCHING IN REGULAR SEA

Considering a platform and the sea to be a single dynamic system, the interaction between a platform and the sea can be described using Lagrange's energy function. Then, using Hamilton's method, the nonlinear coupling equations of the platform rolling and pitching in a regular sea can be governed. Finally, the steady-state responses of a platform transporting in a regular sea can be solved by the multiple scales, that is the advanced method of the nonlinear perturbation with multidegree of freedom.
