This paper deals with the dynamic analysis of rotationally periodic structures. In particular, a structure composed of angularly equally-spaced blades mounted on a flexible ring is considered. A simplified model of the dynamical behavior of the structure is obtained by employing a homogenization technique. The eigenfrequencies and eigenmodes evaluated by applying the proposed model are compared to the corresponding ones obtained via a finite-element approach.

Abstract
This paper deals with the dynamic analysis of rotationally periodic structures. In particular, a structure composed of angularly equally-spaced blades mounted on a flexible ring is considered. A simplified model of the dynamical behavior of the structure is obtained by employing a homogenization technique. The eigenfrequencies and eigenmodes evaluated by applying the proposed model are compared to the corresponding ones obtained via a finite-element approach.File in questo prodotto:
