|Abstract: ||There are four main air-related noise generation mechanisms at
the tyre/road interface, which were all categorised more than 20 years
ago. The first one is the so-called ‘air pumping’ mechanism. Two
other air-related phenomena that occur when there are air movements
near the contact patch of the tyre are ‘air resonant radiation’ and ‘pipe resonances’ which appear at the footprint of the tyre. In addition to
these, there is a forth effect, which is mentioned in the literature, that
is occurring due to turbulence effects of the air surrounding the
spinning tyre. There has been less focus on the air related
mechanisms than on other types of tyre noise generation mechanisms.
This paper attempts to add some detail to current understanding of
the air-related noise generation at the tyre road interface and gives
some further information on how to identify the differences due to
these mechanisms. Specifically in the present paper, a solid rubber
tyre running on a vehicle chassis dynamometer is used to study the
first two mechanisms. This is done with emphasis on the time history
of the recorded signal and not on the frequency spectrum, as is more
commonly used. A comparison with existing theoretical models of
these mechanisms reveals some of the strength and weaknesses of the
current understanding of these phenomena.|
