Abstract: A mathematical model for a pneumatic tire was used to compute the horizontal and vertical forces transmitted through the tire to the vehicle axle to provide realistic force inputs for model studies of vehicle dynamic. The present model is valid for the computation of forces through a pneumatic tire traversing nondeforming obstacles, with zero slip. Laboratory tests are described in which static load deformation characteristics and dynamic obstacle-traversal characteristics were obtained. These tests were run with 9.00-14 tires under several conditions of ply rating and inflation pressure. Data from these tests were used to calculate model parameters and to produce time histories of dynamic responses. A computer implementation of the mathematical model is described which produced force and displacement time histories similar to those obtained during the obstacle-traversal laboratory tests. The model produced the essential features of the wave form seen in the laboratory and is therefore a valid representation of a pneumatic tire for dynamic analysis of vehicle on nonyielding terrain.
