Experiment-Based Development and Validation of Mistuning Models for Bladed Disks

摘要

The primary objective of this project was to perform experimental work to further the understanding of the fundamental physics of mistuned bladed disks. The experiments that were carried out during the course of this project have served to corroborate analytical and numerical findings, to validate the computational methods that have been developed to date, and to guide the development of improved models and methods that incorporate the relevant physics. In addition, a pioneering mistuning identification technique was developed, and alternative designs featuring intentional mistuning were examined in a series of simulations and experiments.
