Abstract
Noise and vibration, transmitted from road to the body structure of a typical automotive wheel, considered as an important parameter in automotive NVH (Noise, Vibration and Harshness) performance optimization. Having a reliable and simple finite element model of the wheel structure can significantly reduce time and cost of design. Based on the results of experimental and numerical analyses, the effect of inflation pressure is investigated on the behaviour of a tire in our work. The natural frequencies are measured to describe free vibration of the tire. For observation of the dynamic behavior, harmonic analysis is also carried out. Comparison between numer-ical and experimental modal analyses shows an acceptable accuracy. Better understanding of the complex tire characteristics will contribute to develop tire design strategies to lower the tire/road vibration while less affecting other tire performances
