摘要
采用ANSYS分析了大跨度悬索桥吊杆在端部参数激励下的振动响应及吊杆内力的变化,并讨论了吊杆振动与吊杆内力时程的频谱特性。
The vibration response and the variety of the internal force of a hanger of a long-span suspension bridge under an axial parametric excitation are investigated by ANSYS; furthermore, the spectrum characteristics of the vibration response and the internal force fare discussed in present paper.
