Effect of Speed on Tire-Soil Interaction and Development of Towed Pneumatic Tire-Soil Model

Abstract

The role of soil inertia forces and the effects of strain rate in tire-soil interaction are analyzed. Two methods are developed for the determination of inertial accelerations in tire-soil interaction. The effect of strain rate of soil strength properties is analyzed and recognized as the major contributor to the improvement of tire performance with speed. A mathematical model for towed pneumatic tires and soil is developed for the simulation of towed tire-soil interaction. Towed force coefficient predictions are compared with experimental results.
