Abstract:
1. A method of determining the stress that should be applied to a tire during an indoor endurance bench test, the method comprising the steps of: driving a vehicle along a sample road route; measuring variations in the longitudinal speed and position of the vehicle as it the vehicle travels along the sample road route; and calculating using a processor the inertial forces acting on at least one tire of the vehicle as the said tire travels along the sample road route, on the basis of variations in the longitudinal speed and position of the vehicle; the method comprising the further steps of: transforming the inertial forces and the longitudinal speed from the time domain to the space domain; expanding the longitudinal speed in the space domain by applying a first multiplication factor greater than one; expanding the space by applying a second multiplication factor greater than one and equal or greater than the first multiplication factor, and resampling the expanded longitudinal speed and the inertial forces with respect to the expanded space; and retransforming the resampled longitudinal speed and the resampled inertial forces from the space domain to the time domain.
