Formatted abstract
Modelling the lateral dynamic response of railway tack is one of the important steps to predict the growth of rail corrugation. In this thesis, 3-dimensional standard gauge and narrow gauge railway tracks were built and the lateral dynamic behaviours of the tracks were investigated. The proposed models were calibrated by impact hammer test results. Experimental results in the frequency range of 100-500 Hz show that there are three resonances under forced frequency response analysis. A pinned-pinned mode of vibration occurs at 380 Hz. For the narrow gauge track model, it was found that a change of railpad loss factor has a significant influence on the magnitude of the lateral dynamic response, but the influences from the other changes of stiffness and damping parameters are very little.
