Dynamic stability of multilayered beam with bolted joints

摘要: Dynamic stability of elastic systems deals with the study vibrations induced by pulsating load that are parametric respect to certain form deformations. An important aspect in analysis dynamic system is establishment regions space which unstable, these known as instability. The boundary separating stable zones from unstable called boundaries and plot on a diagram. Beams simplest structural members any machine, mechanism or large structure. Layered structures gaining importance present day use because their good vibration damping characteristics. objective work multilayered bolt jointed beam fixed-fixed condition subjected end force. Finite element method used for theoretical analysis. Experiments have been carried out validate findings. For this test rig has designed fabricated provide required variable loading necessary attachments also simulate fixed conditions. experimental investigations show more than single layered similar condition. improves increase number layers. results matched very well one.
