Development and realization of distributed and adaptive vibration neutralizers

Tuned vibration absorbers for resonances or vibration neutralizers for forced vibrations are a common means to suppress disturbing vibrations. In practical situations however, a number of devices might be considered to be distributed over an elastic host structure. Then numerical optimization methods have to be applied to the problem instead of using the well-known design rules which were originally developed for single-degree-of-freedom systems. Furthermore, adaptation of the tuning frequency of the neutralizers might be considered in order to suppress vibration over a wider bandwidth. In this paper, we will report on the results obtained in the framework of the LOEWE center AdRIA regarding those practical issues in the design and implementation of vibration neutralizers.
