Abstract: In this paper physically motivated and nonparametric models are investigated that predict within some tolerance the response of a semiactive electrorheological (ER) damper that was designed, constructed, and tested. The ...

Abstract: An electrorheological (ER) fluid damper suitable for vibration and seismic protection of civil structures has been designed, constructed, and tested. The damper consists of a main cylinder and a piston rod that pushes an ...
