Abstract

A flexible shaft with surface-mounted piezoceramic sheets and strain sensors is considered which suffers from resonance and self-excited vibration. Frequency domain models, time domain simulations, and control experiments are used to analyze active modal damping and active modal balancing methods. The generation of electric power from cyclic straining of rotor-fixed piezoelectric material is studied and several self-powering devices for condition monitoring and vibration control are proposed.
