Abstract
A multiharmonic frequency domain analysis combined with a Craig-Bampto n component mode synthesis is presented to compute the dry friction da mped forced response of blades. The accuracy of the analysis is establ ished, for a cantilever beam with a dry friction damper attached, by c omparison with experimental results and time domain analysis. The meth od has then been applied to a model fan blade damped by a blade to gro und damper.
