Practical application of energy-recycling semi-active vibration suppression method to an actual satellite structural model

Experiments of vibration suppression were executed by implementing the energy-recycling semi-active method using piezoelectric transducers. The purpose of the experiment is to practically apply the method, of which performance has been proved numerically and experimentally using the truss model, to an actual satellite structural model and investigate an effectiveness and problems of the practical application. Although the damping performance in the experiments was not so good in comparison with that in the truss model experiments, it was found that the energy-recycling semi-active method worked on an actual satellite model and showed better performance than the conventional semi-active method. The description of the energy-recycling method, the configuration and the results of the experiments are presented. Copyright IAF/IAA. All rights reserved.
