摘要
采用有限元法、改善的动力缩减法和数值积分法研究了减小船体艉部振动的非线性碟簧动力吸振器的宽带数值优化设计 ,通过结合具体的应用实例系统讨论了非线性碟簧动力吸振器的线性刚度、粘性阻尼、Coulomb阻尼、刚度非线性和弹簧组合系数与抑振带宽的关系 。
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
