ABSTRACT
ABSTRACT: The present paper deals with the experimental validation of the first-order tyre dynamics approach as it is applied in the semi-physical tyre model TMeasy. Firstly it gives a brief derivation of the modelling principle, followed by a description of the accomplished measurement procedure. From the measurements, a set of model parameters of the considered tyre is identified, where no particular fitting parameters for the tyre dynamics are needed. Based on these model parameters, the related dynamic simulations are carried out. The resulting tyre contact forces will then be compared with the measurements after they have been converted into the central axis system of the wheel force transducer. The comparison shows that the applied model describes the behaviour quite well within a defined operation point, but for investigations with high frequency steer inputs and high slip angles, a more detailed model is needed.
