Noise generated by rail vehicles has become an issue of increasing concern, particularly in urban and interurban contexts where the demand for sustainable and efficient mobility has driven the expansion of rail networks. Consequently, there is a growing need to optimise vehicle design and component performance to comply with stringent regulatory requirements and to enhance the quality of life for passengers and residents living near railway lines. These efforts increasingly rely on predictive modelling, which significantly reduces both costs and development time while enabling the design of quieter vehicles and infrastructure.
The thesis focuses on the development of sound radiation models aimed at estimating the noise generated by the wheel and rail during rolling. These models will be integrated into a wheel–rail interaction model to simulate rolling noise and curve squeal. Results will be validated against pass-by noise measurements.
