During many years the automobile industry used only experimental techniques to develop its products. However, in the last decades technological advances of computers and the development of sophisticated simulation software provided considerable time and cost reduction associated with the development of new vehicles. From this new point of view, experimental tests are not eliminated instead they are necessary to predict component parameters for model simulation and validation. The use of simulation software helps the engineer in design solution finding as well as its evaluation under different conditions. However, the model must represent the real system behavior with highest accuracy. To do this, experimental tests with a prototype must be accomplished and the results compared with the simulation. In this work, the numerical validation of a short long arm suspension (SLA) model will be compared with a real prototype. The reduced scale prototype was built and experimental tests were conducted for different suspension parameter adjustments. The simulation was made by means of multi-body model using the commercial software ADAMS®. The simulation results shown that the computational model could represent the prototype behavior adequately.
