Abstract: vibrations is an extremely important issue to consider when designing various systems. It may lead to discomfort and malfunction or in some cases collapse of structures. To compensate for these vibrations different types of damping devices can be introduced and applied. The main scope which the following work addresses has been to look at standard methodology which enables determining the hysteresis from predefined steps for range of measurements which will be applied later on specific system integrated with Magnetorheological damper.The mathematical equations that lie behind the Bingham, Dahl, Lugre and Bouc-Wen have been studied to describe the behavior of the MR damper. The hysteresis equations of Bouc-Wen, Lugre, and Dahl have been modeled and simulated in Matlab/Simulink. The different parameters in the models have been manipulated and analyzed to determine the effects on the outcome. The hysteresis models of Bouc-Wen, Dahl and LuGre have been analyzed and com!
pared analytically to show the difference in the models. At last the Bouc-Wen model was implemented together with the SAS(Semi Active Suspension) experimental system. The model parameters were tuned manually to fit the response of the system. This paper introduces the methodology flowchart which can be implemented and generalized for any kind of dampers, in the following work, the methodology was used to find hysteric behavior of MR damper with different mathematical models.
