Friction Damping of Interlocked Vane Segments: Validation of Friction Model and Dynamic Response

Aim of the present work is the validation against experimental results of the dynamic calculation of a vane segment with two friction contacts. The segment is in contact with two adjacent supports as in the experimental setup [1]. An empirical friction model derived from the experiments is introduced. The calculation has been performed for different interlocking values (different values of force normal to the contact surfaces). An analysis about the dependence of the parameters of the adopted empirical contact model on the hysteresis cycle shapes has been performed.Copyright © 2002 by ASME
