| Abstract: | 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. |
