Vibration in most machines, vehicles, structures and buildings are undesirable. Vibrations in a system result in unpleasant motions, development of dynamic stresses noise and discomfort which may lead to fatigue failure of the system and reduction in performance. The control of vibration can be done by passive, active and Semi-active dampers. The semi active dampers are a class of energy dissipating device for which the damping may be controlled in real-time. This is achieved by either altering the properties of the damping fluid as is the case for electro- and magneto-rheological dampers or by actuating mechanical components of the damper. The present work aimed to develop a single degree freedom system at the time earthquake. An experimental setup of single degree of freedom system having MRF damper with base excitation was designed and fabricated for low frequency application. Experiments were conducted to obtain dynamic response of the MRF damper in the dry friction state considering MRF damper with no magnetic field and MRF with varying magnetic field. The experimental setup can be correlated to the machine during the earth quake.
