PERFORMANCE EVALUATION OF MAGNETO RHEOLOGICAL DAMPER FOR VEHICLE SUSPENSION WITH SEMI ACTIVE CONTROL SYSTEM -A REVIEW

The vehicle suspension is used to minimize the vibration transferring from the irregular road surfaces. The control of these vibrations is still to be the booming field for the researchers. The increasing demand of ride relief and road stability leads to the development of suspension systems with new control strategies and actuating devices which can provide the strong performance. Hence to achieve this semi active control system is adapted to overcome the limitation of active as well as passive suspension system . Semi active control is well known for its low implementation cost,simplicity in construction and lower power consumption than active control. The actuation devices mostly used for semi active control are piezoelectric dampers,magneto rheological damper,tuned liquid column damper and electro rheological damper,out of which the MR damper h as a semi active control and it had been accepted over last several years. MR fluids consist of the oil with iron particles in it. The device forces are adjusted by varying the strength of magnetic field. https://www.ijiert.org/paper-details?paper_id=14080
