The objective of this research is to propose new probabilistic methodologies for the dynamic analysis of themistuning of rotating structures with cyclic symmetry in the low frequency range. The structure under consideration is a bladeddisk. Firstly, a recent nonparametric probabilistic model is used for constructing a direct probabilistic approach, allowingthe dynamic amplification of the forced response on blades induced by mistuning to be analyzed. Particularly, such aprobabilistic approach allows the blade-eigenfrequencies mistuning and the blade-modal-shape mistuning to be modeled withcoherence. Secondly, an inverse probabilistic approach, based on an identification method of the dispersion parameterscontrolling the nonparametric probab...
