MODEL-BASED METHOD FOR DETERMINING THE ROAD HANDLING PERFORMANCE OF A TYRE OF A WHEEL FOR A VEHICLE

摘要

A method for determining the road handling of a tire, comprising descriptions of the tire by means of a first, concentrated-parameter, physical model and by means of a second, finite-element model, a simulation on the second, finite-element model of a selected series of dynamic tests and an application to the first physical model of equations of motion suitable for representing the dynamic tests in order to obtain first and second frequency responses of selected quantities; a comparison between the first and second frequency responses of the selected quantities for determining the concentrated parameters of the first physical model and physical quantities indicative of the drift behavior of the tire.
