摘要
在桥梁车辆振动分析的古典理论基础上,利用ANSYS软件建立了桥梁的有限元模型,通过数值模拟计算分析了不同激振频率的简谐力通过桥梁时,桥体发生的动态响应特征,为移动荷载作用下桥梁振动的控制提供依据。
On the basis of typical theory on vibration analysis of bridge and vehicles, by using the AN-SYS software, a finite element model is established, Through the numerical simulation, the character of dynamic response of bridge is analyzed when harmonic Loads with different frequents pass through the bridge. The research will give beneficial hales for the vibration control of bridge under moving loads.
