摘要
在车辆不同速度作用下桥梁的变形有其复杂性,对其研究为工程界所广泛关注。本文利用AN-SYS软件建立了桥梁的有限元模型,通过数值模拟计算分析了车辆以不同速度通过桥梁时,桥体发生的动态响应特征,从而为移动荷载作用下桥梁振动控制措施的改进提供依据。
The deformation of bridge subjected to vehicles with different velocities is complicated, and some attention has been paid to it in engineering community. By using the ANSYS software, a finite element model is established, and through the numerical analysis, the character of dynamic response of bridge is analyzed when the vehicle is at different parts of the bridge with different velocities, the research will give beneficial rules for improving the vibration control measures of bridge under moving loads.
