Abstract
A modal analysis is performed on a blade and disk assembly of a turbomachine, including selecting a target vibration frequency at which a target amplitude of vibration has been measured for a target node during operation, and deriving modal velocity vectors from the target amplitude at the target node. A transient analysis is performed on a numerical model of the blade and disk assembly, including modeling the connection between the blade and disk such that the connection is characterized by a first degree of flexibility representative of a first set of actual operating conditions at the connection, and introducing a perturbation to the transient analysis at an initial steady state condition by applying the modal velocity vectors suddenly to a plurality of nodes of the numerical model while maintaining the initial steady state condition.
