Influence of ribs on the acoustic behaviour of piano resonant plates
The eigenfrequencies and vibrational modes of a simply supported stiffened rectangular plate are determined by means of perturbation method. Additional eigenmodes are excited by the presence of ribs and the eigenfrequencies are shifted. A qualitative evaluation of the influence of these additionally...
