Simulation methods and physical testing have become an integral part of the development process of vehicles to achieve a high quality of the products at a significant lower time to market. Both virtual and physical methods have evolved tremendously in the past decades due to the progress in hardware and software technology. For instance, in physical fatigue testing it is now possible to control a large number of loading directions and sophisticated software and sensors ensure that loading and damage match the rated level. In the CAE world, Finite Element Analysis, Multi Body Simulation and Fatigue Life Prediction are already capable to describe nearly all physical behavior of complex systems up to complete vehicles. Although the test and the analysis world have progressed quite far there is still a weak link between these two worlds in using the results and methods from the other world each. One aspect to integrate the test and analysis worlds is doing virtual iteration utilizing MBS models and measured signals (e.g. forces, strains) the same way as this has been done about 15 years on servo-hydraulic test rigs. This paper discusses different aspects of linking virtual and physical testing methods. On the one hand simulation can be used to set up, improve and run test rigs more efficiently. On the other hand methods from testing can be used in CAE to generate loads, adapt model parameters or find simpler loads that still deliver the desired test result. In the future it should get practical to simulate tests in full detail before physical testing. All this will help to reduce effort and time during the vehicle development process
