In predicting rolling noise froma railway wheelset, some assumptionsare usually required to make the calculations less complicated and more efficient.In this study, effects of modelling assumptions on prediction ofsound power radiated from a high-speed train wheelset are investigated by using finite element boundary methods.Use is made axi-symmetry allow solution be obtained in terms Fourier se...

Purpose: Measuring is an important process for finding any physical quantity values. Any measurement primary requirement accuracy. Processes are being replaced, improved and automated gradually. Geometric parameter has become one of the most popular processes in all industries. With its improvements, first achievements have begun. The development usage remote measurements to determine wheelset ...

The dynamics of a railway vehicle are driven by the geometry and conditions at the wheel-rail contact. Typically the condition and shape of the wheel and rail are monitored separately and off-line. The work presented here is part of ongoing research into on-line modelbased estimation of parameters in the wheel-rail contact dynamics. This paper outlines a practical approach to estimating a nonli...

To investigate the influence of structural deformation wheelset and track on rail wear in longitudinal lateral directions, a prediction model is established that can calculate three-dimensional distribution wear. The difference between multi-rigid-body dynamic rigid-flexible coupled model, which considers flexibility track, compared terms results show distributions predicted by two models are r...
