A methodology for the prediction of the vibration levels of welded-inpairs low-pressure-turbine rotors is presented. It combines three-dimensional viscous linear aerodynamic analyses with a simple friction model for the fir-tree attachment. Results are presented for an existing rotor and compared with experimental data.
