Özet

The free vibration of a rotating laminated composite beam with an attached point mass is investigated. The Ritz method with algebraic polynomials is used in the formulation. The boundary conditions are considered as clamped-free. Different shear deformation theories (first order and third order) and classical beam theories are used in the formulation. Cross-ply lamination configurations are considered. Effects of the ratio of attached mass to the beam mass, rotation speed, hub ratio, orthotropy ratio, position of attached mass, beam theory and length to thickness ratio are analyzed in detail. Some typical mode shapes are presented in order to illustrate the effects of the attached mass.
