A Laboratory for System Identification of Mistuning in Integrally Bladed Disks

Abstract

The funds received from the DURIP proposal were to be used to purchase a Polytech scanning vibrometer. The vibrometer is being used to make precise measurements of the mistuned modes and natural frequencies of integrally bladed disks (IBRs) in the Mistuning System Identification Laboratory. The resulting data is then used as input to system identification software that is being developed at CMU under a separate Air Force contract. The system identification software then determines the mistuning in each blade. This report documents the development of the vibration laboratory, the types of measurements that are being done, and the research that has been made possible through its use.
