Paper Details

In the last three decades or so, there has been a great deal of interest in the use of controlsystems to mitigate the effects of dynamic vibrational hazards on both Mechanical and Civil Structures.Magnetorheological (MR) Fluids are controllable fluids that respond to an applied magnetic field with adramatic change in rheological behaviour. An MR Fluid is a free-flowing liquid in the absence of magneticfield, but under a strong magnetic field its viscosity can be increased by more than two orders of magnitudein a very short time (milliseconds) and it exhibits solid-like characteristics. MR Fluid Dampers, based onMR Fluids, have been shown to be semi-active control devices that mesh well with application demands andconstraints to offer an attractive means of controlling the intensity of vibrations in structures due to theirmechanical simplicity, high dynamic range, low power requirements, large force capacity androbustness.The structures designed to support the high speed engines are subjected to inherent unbalancewhich causes vibrational problems. The focus of this work is to study the analysis of an aluminium structureusing the Magnetorheological dampers with fluid MRF-132DGwithand without applying magnetic field.And it is observed that the MR Fluid dampers could able to effectively reduce the mechanical vibrations ofstructures.
