• A three-story structural model was equipped with Magnetorheologival (MR) damper, and the structural response was investigated under various excitations. The performance of the prototype MR damper was also studied under various conditions of amplitude, frequency and electric current to the coil in the damper. MR fluid is known as a class of functional fluid whose yield shear stress can be varied by the applied magnetic field strength. Because the maximum yield snear stress is far larger than ER fluid, whose propertied can be controlled by the applied electric field strength, MR fluid is thought to have great potential in applying in mechanical and civil engineering field. A neural network was applied to an adaptive vibration control system for the structure and the performance of the control system was verified by simulation and experiment.
