Rail corrugation is usually generated in modern railway transportations, such as high-speed railway, urban and heavy-haul railway. It one of the major excitations to wheel–rail dynamic interaction, which will cause extra vibration noise, failures, or even risk derailment vehicle its components. A dynamics model a locomotive considering traction power from electric motor wheelset through gear tr...

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...

A combination of instrumented wheelset measurements and numerical simulations axle bending stresses is used to investigate the consequences evolving rolling contact fatigue (RCF) damage on a passenger train wheelset. In field test campaign, have been monitored using with four strain gauges mounted axle, while evolution wheel tread (out-of-roundness) has measured regular occasions. The signals a...
