Abstract
A method is presented for predicting a noise/comfort performance in a cabin of a vehicle with a body-shell and a suspension system linked to the body-shell by at least one point of attachment, with the vehicle rolling at a given speed on a rolling device with a macrorough rolling surface. The method includes: determining a global transfer function of the body-shell, determining a global admittance of the body-shell, determining an impedance of the suspension system, determining, while rolling on the macrorough rolling surface, lockup loads of the suspension system, and combining together the global transfer function of the body-shell, the global admittance of the body-shell, the impedance of the suspension system, and the lockup loads of the suspension system to obtain a prediction of noise/comfort performance (P) inside the cabin.
