THE EXPERIMENTAL DETERMINATION OF TYRE MODEL PARAMETERS

摘要

This report describes the analysis of a series of experiments on pneumatic tyres which were designed to test the various hypotheses regarding the deformed shape of a tyre during the steering process.nThe experiments consisted of several separate tests first described in Ref. 1 and 2.na) The application of a point lateral force or a moment at one position on the tread band which is restrained at the centre of the wheel, and the measurement of the resulting lateral deflection of each point of the tyre perimeter.nb) The application of a uniform force around the tyre perimeter on a hollow cylindrical former and applying a load at the centre of the wheel.nc) Direct determination of tread band tension by cutting the tread band and bridging the cut by a dynamometer.nd) Estimation of the bending modulus of the tread band by test on sections cut from the tread band.
