Sensitivity analysis for tire/road interface model
Résumé
The aim of this work is to highlight the more influential parameters involved in a tire/road interface model, the Magic Formula (also called Pacejka model), commonly used in the automotive and aeronautical domain. The paper takes an interest in the basic function of Magic Formula, which is nonlinear and depends on six unknown parameters to be estimated. A sensitivity analysis based on the approach of Sobol is carried out. It is then emphasized that only two parameters over the six contribute significantly to the uncertainty of the output of this model.
