Abstract
The present work presents analytical modeling of the suspension vertical dynamics of an off-road vehicle and the methodology of experimental validation of the same. For this, a rapid and low complexity test was developed with the acquisition of data made through a compression load cell. With this methodology, it was possible to collect the conditions to be used in the project phase, in order to evaluate the changes related to the previous project and to verify improvement opportunities. With the adoption of the methodology presented, it was possible to improve the dimensioning of the suspension components for vertical impacts, being the most significant improvement in the knuckle which safety coefficient increased from 0,9 to 2,7.
