AB  - Magnetorheological dampers and actuators are based on the physical principle of non-Newtonian
fluids and its behavior when under the presence of a magnetic field. A good mathematical approximation of this
phenomenon is the Bing-Ham Model with the inclusion of the Bouc-Wen hysteresis which evaluates
the non-linearity of the power ratio vs. velocity damping model. This study presents a proposed test for the
identification process also experimenting with various operating conditions in which this type of actuator can
be used such as in vehicle suspension systems, vibration control or prosthetic devices. The study began
exploring various models representing the dynamic characteristics of these actuators, so that, to determine the
state variables to be monitored. From the models studied it was determined that the test bench must consider
the position obtained through a LVDT sensor and the current drawn by an electric motor as inputs as well as
the damping force according to the speed variations as output, this is measured by a load cell. Dimensioning
according to the ranks of the selected actuator operation was performed (RD-8040-1 Lord), so, minimum and
maximum strength and speed at which the system will be subjected were defined in order to assess the full
dynamics of the system. Therefore, a hardware and software based architecture is proposed along with a
graphical user interface that allows applications to be used for identification and control of this actuators.
