| Abstract: | The mathematical model of ship nonlinear rolling on the basis of taking into account all factors that affect ship rolling is presented in this paper.The analytical solution of ship nonlinear rolling was obtained using the multi-scale method which is widely used in nonlinear vibration theory.The parameters in the analytical solution were identified by test data, and the analytical solution was validated. |
