| Abstract: | By applying finite elewent method,dykamic reduction method and munerical integration,the numerical optimun design of a nonlenear dynamic vibration absorber using dished spring for vibration damping at hull stern is proposed.Combined with a practical calcalation,the effect of linear stiffness,viscous damping. Columb damping and stiffness nonlinearity of the dynamic vibration absorber on the suppresion bamdwidth is discusseol.This paper attempts to develop a theoretical method to investigate the nonlinear dynamic vibration absorber of complicated stracture such as a hull beam at stern |
