Damping of longitudinal vibrations of a cylindrical rod

Oscillation of an underground cylindrical rod located in an infinite medium and equipped with a dynamic vibration damper is considered. The vibrations of the structure occur from the action of harmonic forces located along the longitudinal axis of the bar. The possibility of decreasing the vibration...

description Oscillation of an underground cylindrical rod located in an infinite medium and equipped with a dynamic vibration damper is considered. The vibrations of the structure occur from the action of harmonic forces located along the longitudinal axis of the bar. The possibility of decreasing the vibration amplitude using a two-mass absorber with a series connection of masses is considered. The parameters of the absorbers were optimized for different values of the environmental parameters. It was found that with a fairly high operating efficiency of the main damper for damping the first vibration mode, an additional damper can be used to reduce the amplitude of the second resonance. In this case, both dampers operate on separate vibration modes. Using a two-mass absorber can significantly reduce the formation of an underground structure. In this case, the expansion of the quenching zone was achieved in comparison with a single-mass quencher.
