Abstract:
A machine was built to study non-rolling tire stiffness and damping coefficient of agricultural tractor tires in the vertical direction. Measurements of static deflection and contact area on a rigid surface can be performed. During dynamic experiments, a sinusoidal deflection function is imposed to the test tire to determine dynamic stiffness and damping coefficient. The experimental setup and methodology are described in this paper. A complete sample test and its analysis are also presented.This paper was approved for publication by the Director of the Louisiana Agricultural Experiment Station as publication number 93-07-7238.
