| Abstract: | The interaction vibration between bridge and vehicle is an important problem in bridges of highway and railway.The numerical methods now usually used need much more time to complete the analysis.With the aim of increasing the computation efficiency,a numerical method which is based on the nonlinear vibration theory is proposed to study the dynamics between vehicle and curved bridge in high speed railway.The program BSNDS is composed to evaluate the method.The simulation proves that the method can decrease the computation time greatly then other models without losing accuracy. |
