23-74 CONSIDERAŢII PRIVIND OPORTUNITATEA UTILIZĂRII MODELULUI SHEAR PENTRU BARE DE DIFERITE LUNGIMI
CONSIDERATIONS THE USE OF SHEAR MODEL FOR
BEAMS OF DIFFERENT LENGTHS
This paper presents a study of dynamic behaviour for different lenghts of
beams, preserving constat section. The natural frequencies on beams, for 8
bending vibration modes after weak axis were determinated using Sh model
and by FEM analysis. For any lenght of beam, the result is pretty good,
acceptable errors.
