COMPARISON OF EXPERIMENTAL AND CALCULATED DYNAMIC AND STEADY-STATE TIRE ADHESION DURING BRAKING --INTERNATIONAL CONFERENCE ON NEW DEVELOPMENTS IN POWER TRAIN AND CHASSIS ENGINEERING AT THE CONGRESS CENTRE, STRASBOURG, JUNE 3-5, 1987. 2 VOLUMES

In their earlier papers, the authors presented certain results obtained in experiments conducted on the "steady-state" tyre adhesion using a single wheel trailer and on the "dynamic" tyre adhesion employing a test vehicle. One of the conclusions was that there was a significant difference between these two groups of results. A considerable error could be made if the steady-state adhesion-slip curves were used instead of the dynamic adhesion-slip curves in predicting the behaviour of a vehicle during braking. It is much better to use the calculated adhesion-slip curves based on the steady state experimental results. A mathematical model of a braking wheel has been made, and it allows for the effects of the vehicle speed, vertical force, braking moment (torque), tyre pressure and the brake activating speed on the tyre-to-ground adhesion. The theoretical results describe very well the behaviour of a wheel during braking and provide a good correlation with experiments.(a) for the covering abstract of this conference see IRRD 814142.
