Abstract:The coupled vibration between vehicles and curved bridge in high-speed railway isstudied, based on which a numrical computational method that is based on the nonlinearvibration theory is proposed to study the dynamics between vehicles and curved bridge in high-speed railway. A corresponding computational software is programmed under Winndows95operation system by using PowerStaton, and a good computation result is obtained. Thenumerical simulation proves that the proposed method can decrease the computation time greatlywithout losing accuracy compared with preciuos other models.
Keywords:structural engineering  numerical simulation  coupled vibration  nonlinearity  coordinate transformation
