In many technical applications undesired mechanical vibrations are a growing problem. Especially in vehicles vibrations can cause a significant reduction of the passengers comfort, which is often not tolerated. These problems reveal the existing urgency to apply specific vibration reduction measures. Besides conventional 'passive' measures, in the last few years a tendency towards 'active' systems, also known as 'smart structures', can be seen. Within the framework of the Fraunhofer project FASPAS, such highly integrated smart structures are developed. The principal aim of these smart structures is to significantly reduce structural vibration in complex systems such as car bodies or machine tools. One result of the presented investigations is the statement that it is possible to design active complete systems with the developing method above described. If possible, it is recommended to simulate and analyse the structure in question to get validated simulation models. By combining these models complete system simulations are possible which offer an insight in the later system behaviour. Hence, a lot ot information can be found in advance that is necessary to design the specific devices in detail. Moreover, different control algorithms can be tested and appraised. Unfortunately, the simulation results of the controlled complete system do not fit too good with the experimentally found ones. Here are further investigations necessary to improve the simulation models.
