Analysis and evaluation of a tyre model through test data obtained using the IMMa tyre test bench

摘要

Nowadays, obtaining results on the forces and torques in a tyre, in controllable and repetitive working conditions in a laboratory, is fundamental for research groups in vehicle dynamics simulations. There is a need, more than a convenience, to own a facility to test tyres of a wide range of dimensions and with versatile and non-restricted operating conditions of functioning. In this paper a group of experimental data obtained from tests on a tyre in the IMMa tyre test bench is presented. With the goals of determining the accuracy of these experimental test data and also the operating performance of the test bench in the steady state, the analytical model of pneumatic tyres for vehicle dynamics simulations reported by Gim and Nikravesh is employed.
