This paper aims at demonstrating the importance of the correct validation of simulation models. Although correct model validation is often taken for granted, a large portion of published research does not pay adequate attention to this issue, resulting in models that are not adequate validated. The importance of validating the model for the correct parameters will be demonstrated by means of a case study which entails the modeling and experimental validation of a multi-leaf spring suspension system. Experimental measurements include the spring force as well as the forces acting at the suspension attachment points measured by two six component load cells. The six component load cells make it possible to validate the resultant force as well as its application point at the suspension attachment points. The result of the qualitative comparison of the experimental and model data shows the importance of validating the model against the parameters of interest. It also shows that extrapolating correlation results to other parameters may not be a good assumption in many situations.
