Vehicle/Track Impact Due to Passing the Transition between a Floating Slab and Ballasted Track difference between the two kinds of track. A time-domain model is developed for the vehicle/track interaction and the characteristics of the impact are analyzed by numerical simulation using the model. Calculation results show that the wheel/rail impact load at the transition is moderate and its pe

Recent Developments in Operational Rail Noise and Vibration in NSW, Australiascription of a number of recent mitigation projects, programs and techniques. It covers mapping of rail noise on a number of urban lines for the prioritisation of mitigation options; detection of “noisy” wheel defects; and the application of source noise control. It also describes mitigation measure

Experimental Validation of a Numerical Model for Subway Induced Vibrations dynamic interaction between the train, the track, the tunnel and the soil. The periodicity or invariance of the tunnel and the soil in the longitudinal direction is exploited using the Floquet transformation, which allows for an efficient formulation in the frequency-wavenumber domain. A general an
