| Abstract: | Several methods of modeling the vibration excitation of an automotive tire by its tread pattern were developed, ranging from a very simplified approach with an equivalent single point, single line scanning procedure to multi-point, multi-line scanning. This results in a periodic model, since even for a so called random tread pattern there is a periodicity corresponding to one tire revolution. Various tread profiles are explored and response spectra for forces and displacement at the suspension point are obtained and discussed. Receptances formulated in terms of the free tire shell modes are utilized. To contrast the force input type models of the tread excitation with the displacement type input of long road waves, the latter is also discussed briefly. |
