EN The paper presents experimental investigation of a horizontally suspended cable with an MR damper attached transversally near the support. The algorithm proposed to MR damper control employs the concept of emulation of a viscous damper wit h an optimal viscous damping coefficient. The algorithm is realized using a velocity feedback with damping force tracking control is applied. Free vibration of the cable with an MR damper operating in passive and controlled modes are investigated. The obtained results indicate that an appropriately controlled MR damper ensures a nearly constant damping level in a wide range of cable vibration amplitudes.
PL W artykule przedstawiono wyniki badań eksperymentalnych układu poziomo zawieszonej liny z tłumikiem MR dołączonym poprzecznie w pobliżu podpory. Do sterowania tłumikiem MR przyjęto koncepcję emulacji tłumika wiskotycznego o optymalnym współczynniku tłumienia. Algorytm sterowania zrealizowano przy wykorzystaniu sprzężenia od prędkości oraz nadążnego układu sterowania siłą tłumienia. Analizie poddano drgania swobodne liny z tłumikiem MR pracującym w trybie pasywnym oraz sterowanym. Wyniki badań wskazują, że opracowany algorytm sterowania pozwala na uzyskanie w przybliżeniu stałego poziomu tłumienia drgań liny w szerokim zakresie wartości amplitudy drgań.
