PROCEDE DE MODELISATION D'UN PNEUMATIQUE EN SITUATION DE ROULEMENT A UNE VITESSE DETERMINEE

摘要

A method is provided for modelling a tire in running conditions at a defined speed. During running, the tire is subjected to a downward vehicle load (Fz) representing a vehicle and to a transverse thrust stress (Fy), and the tire is inclined with respect to a vertical direction by a camber angle (γ). The method includes modelling an overturning moment (Mx) exerted on the tire, in which the overturning moment (Mx) is a sum of at least: a moment (Mx1) produced by an offset of the vehicle load (Fz) by the camber angle (γ); a moment (Mx2) produced by the transverse thrust stress (Fy); a moment (Mx3) produced by a ground reaction (FR) under the vehicle load (Fz), with the ground reaction (FR) being decentred from a reference point (C) of the tire by the transverse thrust stress (Fy).
