Rig test optimization by fatigue simulation verification of simulation by test

Simulation and Test are today co-operation tools in the vehicle development. While both methods were used more or less separately until a few years ago, the combined benefits of both methods are essential for an efficient development. The integration of calculation and test is presented in this paper showing some specific examples from the Structural Durability Laboratory. However, it is generally feasible also in other areas. This connection of simulation and test leads to an increase of efficiency and a reduction of the used prototypes and test parts in the strategy of "Road-to-Lab-to-Math".
