Investigation on computing method of nonlinear vibration of the stayed cable with displacement excitation at the end point
摘要
Abstract
According to the theory of cable dynamic ,a large amplitude nonlinear dynamic function of the cable with displacement excitation at the end point was deduced by considering the relations between different order modes of nonlinear vibration in cable .T he influence of different sag‐span ratio on vibra‐tion characteristics of the cable was discussed based on the parameters of a real cable .A numerical result based on cable nonlinear dynamic function was calculated by Runge‐Kutta method ,proved the reliability of the theoretical model ,by comparing with the result of nonlinear FEM dynamic time‐history integral .关键词
