The development of fast algorithms to simulate large mechanical or mechatronical systems is one aim within the field of mechanics. Therefore the developed models should be as simple as possible and as accurate as necessary. To find this optimum experimental investigations have to be carried out with respect to special physical effects and the real system. The coaction of theory, numeric and experiment gives a better understanding of the investigated system and hence leads to an efficient modelling of the system, which can be transferred into praxis. In this sense the Institute of Mechanics makes research within the following fields: multibody dynamics, nonlinear vibrations, dynamics of machinery, dynamics of vehicle systems, contact mechanics, mechatronics of vehicles, flight mechanics, flight simulation and robotics. Short Description: Teaching and research in multibody dynamics, nonlinear vibrations, dynamics of machinery, dynamics of vehicle systems, contact mechanics, mechatronics of vehicles, flight mechanics, flight simulation and robotics.
