Abstract:
Tyre/road noise is one of the main sources of traffic noise. Different approaches have been made over the years to study the influence of road and tyre design on the noise generation. Often, this has been realized by measurement campaigns where special road surfaces or tyres were built, and either pass-by or CPX measurements were performed. In some cases tyre/road noise was also investigated with respect to human perception by evaluating were also made to investigate recorded signals in listening tests. Both approaches are rather cumbersome as they need specially built tyres or road surfaces. Alternatively, simulations can be used as input data. This allows for a perception-based design of tyres or road surfaces. This paper introduces a method to carry out simulations which are suitable as input data for listening tests. An extended version of the Chalmers tyre/road interaction model is used to allow for calculating sufficiently long time signals in the form of CPX signals and/or pass-by signals. Qualitative comparison is made with measurements.
