Abstract

A model updating approach is proposed in this paper to describe blade disc mistuning by adding point mass elements in each blade model. This approach uses concepts from test planning and model updating methods to select the locations and the values of mistuning elements to match experimental natural frequencies of several blade-alone modes. The case study presented in the paper demonstrates that the updated bladed disc model, assembled from the updated models of the individual blades, provides the capability to predict forced vibration response over a frequency range covering several families of modes of the bladed disc
