Wirth, N.N.WirthOeckerath, A.A.Oeckerath2022-03-052022-03-052017https://publica.fraunhofer.de/handle/publica/25141310.1007/978-3-319-62458-7_13In this paper a mapping procedure for the simulation of flow-induced vibrations in turbomachinery is presented. The exciting pressure fluctuations are computed in the frequency domain using harmonic CFD methods and are mapped to a structural FEM model of the considered turbine component utilizing the {Fraunhofer SCAI} software MpCCI FSIMapper. The frequency response analysis of the structure gives information about the resulting vibration amplitudes and allows realistic fatigue estimations of the flow-excited turbine component. The mapping process is designed for the special needs of applications using cyclic symmetric simulation models. The described method is applied to a two-stage axial turbine.enbook article
