TL;DR: In this paper, a new approach for time-varying (TV) modal parameters identification is proposed, where the entire signal is divided into successive short time windows, and the structure response under white noise excitation is transformed into modal coordinates by the Independent Component Analysis (ICA) method.

TL;DR: In this paper, a method based on Green's function is proposed for the dynamic analysis of a rotor-bearing system with electromechanically coupled boundary conditions, which is supported by two ring-shaped piezoelectric dampers, which has been manufactured in previous research.

TL;DR: In this paper, the parametric instability of a rotor system with electromechanically coupled boundary conditions under periodic axial loads is studied based on the current flowing piezoelectric shunt damping technique, the detailed rotor model is established by the finite element (FE) method.

TL;DR: In this article, the authors derived the analytical solutions for the dynamic analysis of stepped multi-span rotor system, where the rotating shaft's internal damping effect is also considered, by applying variable separation method and Laplace transform method to each segment's governing equation.

TL;DR: In this article, a ring-shaped piezoelectric damper was developed for vibration control of a rotor system, which can produce much or little damping performance depending on the selection of shunt circuit parameters.
