Abstract
A method of forecasting the comfort performance in a vehicle equipped with a test mounted assembly in a selected position, traveling at speed V over smooth ground, with a maximum speed Vmax, by establishing a vehicle transfer function where the assembly has a tire with N substantially identical irregularities on its circumference, regularly distributed to excite the vehicle in a range of frequencies, measuring the forces at the wheel center, and multiplying the forces by the vehicle transfer function to forecast the noise and vibrations.
