Rational parameters of a «damper on the thread» for damping bending oscillations of rigid bus structures
Abstract: The paper deals with the principle of dynamic damping of girder rigid bus structures of the outdoor switchgears. The special «damper on the thread» has been used to suppress of oscillations, which is placed inside the tubular bus conductor and «turns on» when the occurrence of cross sectional oscillations of the bus conductors. The effect of damping is achieved due to the transfer of vibrational energy bus to damper and the dissipation of energy due to dissipative material properties of the damper. The article presents numerical researches of the efficiency of the damper in its various parameters. The rational parameters of a «damper on the thread» are set. The experimental tests data of damping bending oscillations of cantilever tubular section beams with the application of a «damper on the thread» are given in the article.
Keywords: suppress of oscillations, damper on the thread, dynamic oscillation damper, damping, rigid bus.
