Abstract: The mathematical model for a pneumatic tire described in this paper is 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 dynamics. The present model is valid for the case of a pneumatic tire traversing nondeforming obstacles with zero slip. Static load-deformation characteristics and dynamic obstacle-traversal characteristics were obtained in laboratory tests with 9.00-14 tires under several conditions of ply rating and inflation pressure. These data were used to calculate model parameters and to produce time histories of dynamic responses. Computer implementation of the mathematical model produced force and displacement time histories similar to those obtained during the obstacle-traversal laboratory tests. The model produced the essential features of the waveforms seen in the laboratory and is a valid representation of a pneumatic tire for dynamic analysis of vehicles on nonyielding terrain.
