Outline of Final Research Achievements

In order to identify lug excitation force, the shaft displacement and the shaft force during rolling motion are measured by rolling test. Then, the tire is modelled as a circular rigid ring and the equations of motion are derived considering ground contact and rolling motion. From the derived equations of motion, tire ring displacement is identified from the measured data using least square method. The validity of this identification are confirmed by comparing the measured shaft force with the calculated shaft force using the identified tire ring displacement. Finally, the lug excitation force are identified from the measured shaft displacement and the identified tire ring displacement.
