Computer-aided engineering (CAE) is widely used for designing and assessing various types of engineering products. In automotive industry, where the product cycle has become shorter than ever before, implementation of CAE model is actively engaged. The biggest issue on active usage of CAE is to build a high-fidelity computational model. One research field, called Validation and Verification (V&V), has been involved in enhancing the credibility of CAE model through numerous studies. Most of V&V studies focus on statistical model validation which considers various sources of uncertainty. For a large scale model, for example vehicle system model, hierarchical approach aids improving the credibility of CAE model from the bottom level to the top level of an engineering system. In this study, case studies of statistical model validation on steering column and suspension are introduced.
