From Real to Virtual Tyre - Tyre Model Parameterisation

A consistent process for tyre characterisation has been established by IABG with which tyre data for driving dynamics related applications are generated and tailored to the requirements of driving dynamics simulation. This article provides an overview of the test stand design, the measuring method, the data preparation and the parameter fitting of a Magic Formula tyre data record using the parameter fitting programme MF-Tool. The flat track test stand accommodates all types of tyres, copies driving manoeuvres, including wheel load, slip angle, camber angle and driving/braking, high-dynamically and presents a variety of road surfaces. The measuring channels and sampling rate are adapted individually but normally number 32 at 1 ms intervals. Comprehensive evaluation software is then used to process the measured data. The stages in the parameter optimisation process using MF Tool are listed. Aspects to be considered in the fitting of a Magic Formula dataset are discussed including longitudinal slip and the effect of lateral forces.
