Abstract: A method for predicting the comfort performance (noise, vibrations) in the cabin of a vehicle fitted with a prototype suspension system when the vehicle is rolling at a given speed on a rolling apparatus made of at least one obstacle, consisting of obtaining an overall transfer function for the vehicle fitted with a reference suspension system, measuring the forces that act at the attachment points of a prototype system, and calculating the noise and vibration outputs by multiplying the overall transfer function by the forces acting at the attachment points of a prototype system.
