In this study, the following studies have been carried out(1)Test on a typical MR damper employed in this study was carried out, Neural network model based a direct model and a inverse model were established. The performance of the models were cpmpared with the Bingham model and the hyperbolic tangent model. Results show that ANN model can describe the mechanical behavior of MR damper perfectly as a nonparmetric model.
