Vibration Analysis of Simply Supported Magneto Rheological Fluid Sandwich Beam

Abstract:

Vibrations are unwanted in most of the day today usage especially in mechanical machines, civil structures, aerospace industries and automotive parts. It is usually to get the rid of these vibrations by using magneto rheological fluids. A magneto rheological fluid provides viscous damping which gets added up when magnetic field is applied. The damping properties of fluid get multiplied and natural frequency of the body under observation also changes, using this technique the three layered MR fluid sandwich beam was fabricated and tested it for undamped and damped conditions. The controllability of variations in the various dynamic parameters like natural frequencies, vibration amplitudes and damping factors was observed. Keywords: Magnetorheological fluid, MRFluid sandwich Beam, Natural frequency, Damping factor, Damping coefficient.
