N2 - In this contribution, the effect of impulsive parametric excitation to the modal energy content of torsional systems is investigated. First, it is shown analytically that impulsive parametric excitation allows to transfer vibration energy between sets of modes of vibration. Transferring vibration energy from lower to higher modes allows to utilize the damping properties inherent in a mechanical structure much more effectively. This leads to a faster decrease of the overall energy content, and hence, of the vibrations of a mechanical system, compared to the case where no impulsive parametric excitation is present, as it is demonstrated with some numerical investigations.
