摘要: Application of nonlinear energy sink in annihilating self-excited oscillations a slightly modified experimental and theoretical torsional vibration model drill-string with real parameter values is studied this article. Various configurations have been examined order to procure steady-state responses less time expand the range existence stable equilibria. Moreover, applied modification resulted more realistic response. It proven that attaching different components would help acquire better and/or improve applicability sink.
