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.
