Application of a multiple-beam model for lateral vibration analysis of a discretely supported rail at high...

In this paper a multiple-beam model of the rail, which allows all the essential deformations caused by the lateral vibration, has been applied for studying the lateral vibration behavior related to the discrete supports. Detailed investigation of the lateral vibration of a discretely supported rail has been carried out using a Green's function matrix and the superposition principle. Good agreement between the predictions and measurement data has been reached in terms of accelerance.
