- The paper presents results of laboratory investigations of a vibrating three-layer cantilever beam with magnetorheological fluid. The goal of the study was to determine changes of the acoustic field around the vibrating beam caused by modifications of the magnetorheological fluid properties. The experimental studies have been carried out on a dedicated measuring stand. The construction of the measuring stand allows fixing one end of the beam in a holder attached to the moving part of the electrodynamic shaker. The magnetic field is produced by an external electromagnet. During the measurements the beam displacements and the acoustic pressure have been simultaneously registered. Frequency analysis of the registered signals has been carried out in 1/12 octave bands near the second natural frequency of the beam. The results reveal that the acoustic signal emitted by the vibrating beam decreases when the magnetic field is applied.
