In addition to a full vehicle model, a suitable component model is necessary to describe the vibrations at the component correctly. Therefore, particular attention is given in this work to the modeling of the component and methods to couple it to the car body. Extensive experiments were performed at diverse locations of the vehicle. Comparisons of these measurements and simulations at characteristic locations at the vehicle body and the body-fixed component are presented. The good correlation of numerical and experimental results are promising for future virtual component testing. Covering the reliability of vehicle components from Robert Bosch GmbH, extensive tests are carried out before releasing these modules to customers. Components which are directly attached to the car body (e.g. control units, hydraulic units, sensors, etc.) have to endure in particular vibrations due to road excitations. Therefore, ride tests over specific uneven roads are performed with prototypes to determine the vibrational load on these components. On the other hand, numerical simulations using a full vehicle model offer possibilities to reduce clearly the experimental effort and therefore the connected costs. In addition, simulations can support very efficiently the analysis and comprehension of important effects of the vibrating system.
