Abstract
Full vehicle multibody models are widely used to improve handling and ride comfort performances of passenger cars. However, when focusing on body, it is difficult to validate the simulation results as the forces at the body/suspension interface cannot be measured. Moreover, body results cannot be easily correlated to the subjective handling perception. In this paper, we present a new methodology to analyze the contribution of body flexibility to the handling performances of a passenger car from experimental data. This method, using operational measurements and body measurements, allows in a first step to identify the body forces and in a second step, to analyze the contribution of the body modes during handling maneuvers or for ride comfort.
