SOME CONSIDERATIONS ON MODAL REANALYSIS OF NONCONSERVATIVE DYNAMICS SYSTEMS BY THE GENERALIZED RECEPTANCE METHOD

A structural modification technique which takes into account the dampi ng parameter is introduced in this paper. The applications described a re the extensions of a method based on the Receptance Approach initial ly developed by Palazzolo. Numerous efforts have been made in order to take into consideration the dissipative characteristics of the mechan ical structures. Specific cases of modifications can lead to simplifie d algorithms and, as a consequence, to outstanding results. The conclu sions, which have been drawn up, show the important reductions in term s of computational times but also in terms of memory size, that we can expect when this method is implemented in practical engineering desig n.
