摘要
在考虑斜拉索静平衡时索曲线的基础上 ,建立了斜拉桥索大幅振动的非线性动力方程 ,采用傅立叶级数法研究求解了斜拉索非线性固有振动方程。还通过实例计算对斜拉索大幅振动特性进行了讨论分析。
The nonlinear dynamic equation of large amplitude vibration of cables in cable-stayed bridge is founded with considering the curve form of cables in static equilibrum.The nonlinear natural vibration equation of stay cables is solved by using Fourier's series.The large amplitude vibration character of stay cables is discussed via calculation of concrete examples.
