Adaptive Vibration Reduction
Today the implementing of adaptive structural functions which facilitate an adaptation to varying operational conditions by continuous intervention in the structural-dynamic qualities, can be recognized as an outstanding method to reduce vibrations. Additionally, transducer materials are switched in the structure´s mechanical load paths and their sensory and actuator functionality is linked with a ´regulation-technical‚ Intelligence´. The active manipulations of the disturbing or disturbed systems as well as the interference into the transmission circuit between these constitute the fundamental attempts of vibration reduction. After detection of disturbance and suitable signal processing, actuator signals are introduced into the structure corresponding to the frequency, amplitude and phase, according to the vibrations´ character. The active manipulation of the system as well as the interference into the transmission circuit can cause a damping or decoupling of the source, i.e. a vibration cancellation.
