| Abstract: | Calculation of dynamic response for ship beam coupling with nonlinear disk spring dynamic absorber is discussed by using finite element method, dynamic reduction method and time integration method. Through specific practical application, the effect of linear stiffness, viscous damping, stiffness nonlinear coefficient and Coulomb damping of nonlinear dynamic absorber on suppression bandwidth is investigated by using numerical optimum method. Some conclusions are obtained and they can serve as the guidline of broadband optimal design of nonlinear disk spring dynamic vibration. |
