Abstract |
A set of theoretical models has been prepared which describes the noise generated by tire/road interaction. The mechanisms considered are air pumping and carcass vibration. The models begin with a set of thin shell equations describing the motion of the belt of a radial ply tire, as derived by Bohm ('Mechanisms of the Belted Tire', Ingeniur-Archiv, XXXV, 1966). Structural quantities required for these equations are derived from material properties of the tire. The rolling shape of a tire is computed from the steady-state limit of these equations. Air pumping (monopole radiation from tread voids) is calculated by assuming that tread elements move passively on the deformed tire. Vibrational response of the tire is treated by the full time-dependent shell equations. The force input at the tire/road interface is calculated on the basis of tread geometry and distribution of contact patch pressure. This input is physically equivalent to the impulse distribution models widely used in the tire industry for tread pitch randomization. Subsequent radiation of sound is calculated by a Raleigh integral. |
