The paper concers dynamic properties of rotating shafts, subjected to structural unbalance that excites transverse vibration. The shaft is made of an active composite containing piezoceramic fibers (so-called Piezoelectric Fiber Composites- PFCs). Efficiency of the applied method of active reduction of the vibration is discussed in the paper. Theoretical fundamentals of the method based on the proportional and velocity feedbacks are presented. Simulation results are shown in the form of aplitude-frequency characteristics. The investigations prove that the application of the active laminates, as elements structurally integrated with piezoelectric actuators, is an efficient tool for reducing resonant vibration amplitude in rotating shafts.
