Physically explicit theory of standing waves in tyres at high vehicle speeds
conference contribution
posted on 2010-11-16, 16:03 authored by Victor V. Krylov, O. GilbertIn the present paper, a new physically explicit theory of tyre standing waves has been developed. The
theory is based on a tensioned beam model of a tyre. Simple analytical expressions have been derived for
the amplitudes and shapes of generated waves and for the most important parameter characterising the
phenomenon of tyre standing waves – the vehicle critical speed beyond which the standing waves occur.
The main conceptual idea of this new theory is that generation of tyre standing waves is of the same
physical nature as generation of Mach waves in acoustics, Cherenkov waves in optics, water waves from
moving ships, and bow waves from high-speed trains in railway tracks, not mentioning the others. The
performance of the theory is examined by varying the tyre parameters and by comparing the results, where
possible, to other similar work. The obtained predictions show that the developed theory explains and
predicts the phenomenon of tyre standing waves surprisingly well, given its simplicity and the uncertainty
in the tyre parameters used in calculations.
