“…A variety of tyre models have been developed to analyze vehicle handling, comfort and tyre wear [29,30]. Few models are able to predict the effect of road irregularities [31]. Models that do consider the effects of road texture often aim at the prediction of tyre/road noise.…”

“…The first approach, very popular because of its intrinsic simplicity and the low computational cost, particularly suitable for the real-time applications, avoids the tire physical modeling and determines the interaction forces on the basis of empirical models, as “Magic Formula.” 11,13,14 In this case, the greatest challenge engineers tackle adopting the empirical models concern the tedious identification process of a suitable coefficient parameters set on the basis of tests to be carried out for each tire in analysis. 15,16…”

“…The second approach involves physical system modeling, with its geometrical and physical characteristics, resulting in obviously more onerous from the computational point of view, but it also allows a deeper understanding of the complex phenomena related to the tire behavior in its interaction with vehicle and road. 17,18…”

A tire is an extremely integrated and multi-physical system. From only a mechanical point of view, tires are represented by highly composite multi-layered structures, consisting of a multitude of different materials, synthesized in peculiar rubber matrices, to optimize both the performance and the life cycle. During the tire motion, due to the multi-material thermodynamic interaction within the viscoelastic tire rubber matrix, the dynamic characteristics of a tire may alter considerably. In the following paper, the multibody research comfort and handling tire model is presented. The main purpose of the research comfort and handling tire is to constitute a completely physical carcass infrastructure to correctly transmit the generalized forces and torques from the wheel spindle to the contact patch. The physical model structure is represented by a three-dimensional array of interconnected nodes by means of tension and rotational stiffness and damper elements, attached to the rim modeled as a rigid body. Research comfort and handling tire model purpose is to constitute a structural physical infrastructure for the co-implementation of additional physical modules taking into account the modification of the tire structural properties with temperature, tread viscoelastic compound characteristics, and wear degradation. At the stage, the research comfort and handling tire discrete model has been validated through both static and dynamic shaker test procedures. Static test procedure adopts contact sensitive films for the contact patch estimation at different load and internal pressure conditions, meanwhile the specifically developed sel test regards the tire dynamic characterization purpose at the current stage. The validation of the tire normal interaction in both static and dynamic conditions provided constitutes a necessary development step to the integration of the tangential brush interaction model for studying the handling dynamics and to the analysis of the model response on the uneven surfaces.

“…A great number of studies, both experimental and theoretical, have been performed [1] to derive the tyre characteristics of cars running on hard (either smooth or rough (paved)) roads. Accurate mathematical models for tyre-road interaction, validated for a wide range of operating conditions, are available [2,3]. When vehicles are running on unprepared terrain (such as a farm tractor working on a field), the tyre characteristics have to be assessed properly and, although a considerable number of papers have been published on this topic , more accurate measurements are still needed.…”

A number of experimental activities designed and undertaken for deriving the\ud characteristics of farm tractor tyres are presented. By means of a proprietary measuring hub\ud the three forces and the three moments acting at the hub of a farm tractor wheel have been\ud measured, at different combinations of lateral and longitudinal tyre slips. Tyre steady state\ud characteristics have been derived both on hard asphalt road and on soft soil. The validation of\ud the measurements of tyre characteristics has been performed indirectly by introducing the data\ud referring to tyre characteristics into a detailed mathematical model of a farm tractor. A\ud number of actual manoeuvres have been simulated. The satisfactory agreement between\ud simulated and measured results has provided the necessary condition for the validation of the\ud tyre characteristic measureme nt process
