text: Numerical predictions of the forced vibration of a disc assembly including
frictional effects between the shrouds are presented concerning engineering needs
for the blade design process. Assuming a tuned disc assembly, numerical static,
free and then forced vibration analyses of a shrouded turbine blade measured in
the spin pit are performed systematically. For the excitation forces of an air
jet evaluated from the fairly linear behavior of the experimental blade resonance
peaks, the reliability of the proposed approach is validated through the very
close agreement of the computed and measured resonant peaks. These resonant peaks
demonstrate either a fairly linear behavior or a non-linear one like the jump
effect of blade resonance amplitudes, or elastic impacts between the shrouds.
Also, the damping performance for different contact configurations between the
shrouds is numerically analyzed. These numerical results indicate that the shrouds
generate higher frictional damping for small angles (0--30 deg) between the circumferential
direction and the normal vector to the contact surface. Copyright {\copyright}
