Tire/road noise: Time domain Green's function for the orthotropic plate model

The impulse response (Green's function) of a tire, modelled by a thin ortho tropic plate under tension on an elastic support, is evaluated analytically in the time domain. The approach uses the circular property of the tire an d Poisson's formula. Comparisons are made with the values obtained by perfo rming an inverse Fast Fourier Transform on the Green's function derived in the frequency domain.
