Vibration characteristics of sandwich beam with MR fluid under non-homogeneous magnetic field
In this study, MR Fluid (MRF) sandwich beams were fabricated by treating MRF between two thin aluminum layers. The experiment test rig was set up to investigate the vibration response of the MRF sandwich beam under a non homogeneous magnetic field. The results showed that the natural frequency of the MRF sandwich beam decreased as the magnetic field was moved from the clamped end of the beam to the free end of the beam. It is also obvious that sandwich beam had the properties of left shifting natural frequency when the strength of magnetic field increased in the activated regions.
