Coupled free vibration characteristics of rotating tuned bladed disk systems
V. Omprakash,V. Ramamurti +1 more
TL;DR: In this article, a detailed qualitative study of the coupled free vibration characteristics of rotating turbomachinery bladed disk systems having useful ranges of geometric parameters was carried out by using a three noded triangular shell element having six degrees of freedom per node together with the cyclic symmetric nature of the problem.

Parametric Reduced Order Models for Bladed Disks With Mistuning and Varying Operational Speed
TL;DR: In this paper, a parametric reduced order model (PROM) for bladed disks is proposed, which allows for the variation of rotational speed in the reduced space, by extracting information from sector models at three rotational speeds.
