The magnetorheological (MR) fluids include ferromagnetic and paramagnetic particles suspensions with sizes included between 0.03 and 10 ?m, located in a carrier fluid (usually mineral oil). The complex fluid viscosity strong depends of magnetic field applied. Each particle can be considered a small magnet, which tends to align in the direction of the magnetic field. The magnetorheological fluids have the ability to change their viscosity when they are introduced into a magnetic field, due to the aligned particles in ?chains?. An electromagnetic coil generates a magnetic field by the aid of a small electrical current. The paper aims to study the behavior of the magnetorheological fluids in some types of semi active shock absorbers of the motor vehicles, for different values of the current intensity applied to the electromagnetic coil, in order to improve the comfort of the passengers. The practical objective of the paper consists in the establishment a simple correlation between the magnetic field applied to the magnetorheological fluid, the rod speed, and damping force. The experimental measurements were being performed on a specialized test bench, equipped with transducers which monitor the stroke, velocity and acceleration of the shock absorber piston and damping force developed by the shock absorber. A NI PXI high-speed controller governs the test bench by the aid of NI LabVIEW software.
