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

Thevehicle suspension is used to minimize the vibration transferring from the irregularroad surfaces. The control of these vibrations is still to be the boomingfield for the researchers. The increasing demand of ride reliefand road stability leads to the development of suspension systems with new control strategies and actuating devices which can provide the strongperformance. 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 piezoelectricdampers, magneto rheological damper, tuned liquid column damperand electro rheological damper, out of whichthe MR damper has a semi active control and it had been acceptedover 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
