Abstract
The application of a MR fluid damper for the vibration control of a quarter-car suspension system is proposed and studied.A set of MR dampers is designed
fabricated
and characterized.The mathematical model of this MR fluid damper compared with experimental results for a prototype damper through finding suitable model parameters.A fuzzy logic controller is also developed.The completed system is simulated.Two kinds of excitations
including bump and random road profile
are inputted in order to investigate the performance of suspension system.The vibration responses are evaluated in both time and frequency domains.Compared to the passive system
the vertical acceleration of the sprung mass is significantly reduced for the system with a controlled MR fluid damper.
