Nature of magneto-rheological (MR) fluid to vary its rheological properties under effect of magnetic field can be used to provide rapid and compact vibration control mechanism to critical component of large structure. This study deals with the vibration analysis of adaptive sandwich beam with magneto-rheological core. A lumped parameter model has been proposed which predicts output of magneto-rheological fluid sandwich beam. Effect of varying magnetic field on stiffness and damping coefficient of magneto-rheological fluid sandwich beam is studied. An equivalent single degree of freedom model is obtained from lumped parameter model. Equivalent single degree of freedom (sdof) model is used to analyze effect of varying magnetic field on resonant amplitude of the magneto-rheological sandwich beam.
