In this respect and in order to make sure that newmaterial will not bring about the blade resonant vibrations, the common practice is to use the Campbell diagram approach. This approach only indicates the potential dangers for blade forced vibration. The purpose of this paper is to demonstrate the efficiency of a proposed hybrid procedure for the development of a reliable Campbell diagram, using an updated finite elementmodel and a simplified test setup.
