Railway noise: auralization of the sound radiated from wheel and rail
acoustics, auralization, curve squeal, noise synthesis, Railway noise, vehicle dynamics, Wheel-Rail interactionNoise 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. This has led, in recent years, to the development of several methodologies aimed at predicting the noise generated by wheel–rail interaction. However,

Railway noise: modelling sound radiation from wheel and rail
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

Extension of the Unknown Input Observer algorithm for the identification of lateral railway trackirregularity
To ensure the safety of the railway network, track geometry is periodically inspected by Track Recording Vehicles (TRVs), which are special purpose vehicles typically equipped with inertial and optical sensors. Given their high operating costs, new strategies have been proposed in the latest years to support the condition monitoring of railway infrastructure, relying on instrumented
