摘要
运用哈密顿原理求得了索-桥耦合非线性振动方程组,并运用龙格-库塔数值分析法进行分析计算,利用MATLAB得到了频率比、激励振幅、拉索阻尼比、桥面阻尼比对参数振动的影响,对拉索的减振具有重要意义。
The Hamilton＆#39;s principle was used to obtain line -bridge nonlinear vibration equation and Runge -kutta numerical analysis method was used to do analysis and calculation .MATLAB was used to get the influence of frequency ratio , excitation amplitude, inhaul cable damping ratio, and bridge surface damping ration on the parameter , which is of great significance to decrease of vibration of inhaul cable.
