摘要
本文以已有的车桥振动基本理论为基础,运用有限元软件ANSYS分析了简支梁桥在车辆荷载作用下的振动响应(竖向位移),对比得出了桥面平整度、车速、车型和车辆载重等因素对桥梁结构稳定性的影响作用。
The paper deals with the introduction of the existing basic theory of bridge vibration,analyzes the changes of the beam s deflection （vertical displacement） when the vehicle is traveling under uniform constant force and uniform harmonic force by using finite element software ANSYS,and reaches the conclusion that speed and deck flatness have an impact on stability of bridge.
