This paper describes the development of different active measures to reduce torsional vibrations in power trains. The measures are based on concepts developed for active mounts to reduce the transmission of structure-borne sound. To show the potential of these active measures and investigate their mode of operation to influence torsional vibrations, numerical simulations of powertrains with different active measures were done. First experimental results from tests on an experimental (reduced size) power train were used to align the numerical models. The work was done within the project "LOEWE-Zentrum AdRIA: Adaptronik - Research, Innovation, Application" funded by the German federal state of Hessen, and the Project AKTos: "Active control of torsional vibrations by coupling elements" placed in the research Framework program "Navigation and Maritime Technology for the 21st Century" funded by the German Federal Ministry of Economics and Technology.
