| Abstract | Stator vanes which are used in axial compressors are subject to vibratory fatigue. Furthermore, their manufacturing by assembly of monoblock sectors makes their modelling difficult (cyclic symmetry properties are lost, sensitivity to mistuning is strong). The purpose is to present a robust prediction strategy based on a stochastic model of the structure and on 3D unsteady calculation of the fluid loads. Tests have been performed on the CREATE HP multistage compressor to evaluate the vibratory levels on an instrumented sector to validate the model.
