The aim of this research was to examine the resistance force generated by linear hydro-cylinder type magnetorheological fluid (MRF) damper acting in different regimes. MRF damper performance has been investigated experimentally by using universal computerized material properties testing machine. Measurements of resistance force have been carried out for different speeds of the damper piston motion under different strength of the magnetic field. Dependences of the force on these parameters (speed and magnetic field strength) have been obtained. It was defined, that the force increases practically linearly when increasing strength of the magnetic field and when increasing piston speed.
