Effects on the Vibration of Vehicle-Bridge Coupling System caused by the Nonlinearity of Air Spring
Considering the vertical nonlinearity of secondary suspensions and based on the model of the civil 300km/h railway vehicle, this paper calculates the vibration responses of both vehicles and bridges. The effects on the vertical vibrations of the vehicle caused by the speeds, track wavelengths and track wave amplitudes under periodic irregularity are analyzed in detail. At the same time, it discusses the impacts on the dynamic coefficient, the bridge dynamic deflection, the vertical acceleration of the mid-span and the vertical acceleration of the vehicle body due to different speeds. The results are of some value to evaluate the stability of train operation and comfortability.
