Presentation

From road profile to prediction of rolling tire-induced noise

With vehicle electrification, tire rolling noise is becoming one of the most important sources of cabin interior noise. To enable early-stage NVH performance optimization at the tire and vehicle level in a virtual manner, an efficient frequency domain approach has been developed. True measured road characteristics are converted to inputs for the tire patch through a smart envelopment method. These patch inputs, applied to a novel CAE concept tire model that represents the tire at a given rolling speed, enable the prediction of resulting wheel forces and from there the vehicle interior noise.
