Abstract: Abstract. Bladed disks and blisks are designed to be cyclic structures that ideally have identical sectors. There will, however, always be mistuning, which is blade-to-blade differences that break the cyclic symmetry of ...

Abstract: System identification of dynamic properties is of large interest in the turbomachinery industry to create more accurate computational models and more effective designs. Previous identification techniques are able to ...

Abstract: Component mode mistuning (CMM) is a well-known, well documented reduced order modeling technique that effectively models small variations in blade-to-blade stiffness for bladed disks. In practice, bladed disks always have ...
