W niniejszym artykule przedstawiono wyniki eksperymentów dotyczących drgań własnych poziomo zamocowanej liny, do której dołączono tłumik magnetoreologiczny. Tłumienie drgań zostało zbadane w przypadku zastosowania odpowiedniego sterowania tłumikiem oraz w przypadku, gdy tłumik nie był sterowany. Podstawowym celem badań była doświadczalna weryfikacja zastosowanego algorytmu sterowania. Wyniki pomiarów...
The paper addresses certain aspects concerning the interaction between a cable and a magnetorheological (MR) damper. An essential difference between the displacement of the point where the damper is attached and the displacements of other points remote from the damper has been observed during experiments. The results of experimental data imply non-steady state motion of the damper piston. Twice in...
The paper presents the laboratory facility developed for testing of cable vibrations. The facility was engineered as a part of the research project covering vibration control of cables by the use of magnetorheological (MR) dampers. Potential applications of MR dampers in vibration control of cables are explored. The main emphasis is on mechanical structure, MR damping system, measurement and control...
This paper presents a method for determining the optimal transversely-attached dampers applied to bundle conductors. The differential equation of waves induced in the cable by damper's force was derived and then it was solved by using the method of Laplace transform. The principle of wave superposition was used to describe the resultant wave. The optimal force maximizes the dissipation energy in dampers...
