Abstract (en)

[origin: WO2019211570A1] The invention concerns a method for simulating the physical behaviour of a tyre equipping a stationary or almost stationary vehicle on the ground, the method comprising the following steps for calculating a resultant force transmitted by the tyre between the ground and the vehicle at a given point in time: - modelling (Ea) the contact area in the form of a square surface, - discretising (Eb) the square surface by cutting into slices orthogonal to the direction of travel of the tyre, - for each slice, determining (Ec) the nature of the contact, gripping or sliding, between the slice and the ground depending on the steering angle, - for each slice, calculating (Ed) the elementary force applied to the slice by applying specific predetermined equations depending on the nature of the contact, gripping or sliding, and expressed as a function of dynamic parameters linked to the conditions of use of the tyre and as a function of physical parameters that are characteristic of the tyre, - calculating (Ee) the resultant force by integrating the elementary forces over the entire square surface.
