Abstract: Various technologies are applied to vehicle suspension. The magneto-rheological damper has the ability to adjust the damping coefficient dynamically, and fuzzy logic controller development enables to obtain the desired damping force. The combination of using magneto-rheological damper and controlling it using fuzzy logic will improve the performance of the suspension system. A two degree of freedom quarter car semi-active Bouc-Wen magneto-rheological damper model is used. The controlled magneto-rheological semi-active suspension system is compared with the passive suspension system and optimised passive suspension system. The results showed that the MR reduction in acceleration is about 90%, suspension working space about 81%, the tyre deflection 93% and the jerk about 95% compared with the passive suspension system. Also, the MR reduction in acceleration is about 96%, suspension working space about 77%, the tyre deflection 90% and the jerk about 95% compared with the optimised passive suspension system.
