Parameter calibration in the modelling of railway traffic induced vibrations by use of Barkan
conference paper
Reliable prediction of vibration levels in the surroundings of railway links is dependent on an accurate estimation of model parameters. An important modelling parameter is damping, but because of difficulties in its estimation, particularly in the case of soils, calibration by use of in-situ vibration tests is often wanted. In the case of FEM, such an optimization is not straightforward. As an intermediate step, the Barkan formula, which explicitly handles damping, can be used as a common ground to which both measurements and FEM modelling results are translated. In this article such a side step is investigated.
