Nichtlineare Strukturdynamik

  • Influencing the dynamic properties of metamaterial structures
    In structural dynamics, metamaterials are components whose geometry can be cleverly designed to achieve special dynamic properties such as stop bands (bandgaps). By applying resonators to components, vibrations of the host structure are reduced in pre-designed frequency ranges. This concept can be used, for example, as an inverse mechanical bandpass filter in transmission paths.

  • Vibration Damping with Shunted Reluctance Force Dampers
    Within the Deutsche Forschungsgesellschaft (DFG) funded project, shunted reluctance force dampers are investigated. Reluctance force dampers work contactless and without energy supply offering various advantages, while their nonlinear behavior requires a comparatively high modeling effort. The aims of the project are to improve the calculation of the damping effect in terms of accuracy and computing time on one hand and to investigate their suitability for various damping applications on the other hand.
