Hyperbolic Tangent Model (Version 2) for 200 kN Large-Scale Magneto-Rheological Fluid (MR) Damper

Zhaoshuo Jiang & Richard Christenson
The Magneto-Rheological (MR) fluid damper is a promising type of semi-active device for civil structures due to its mechanical simplicity, inherent stability, high dynamic range, large temperature operating range, robust performance, and low power requirements. The MR damper is intrinsically nonlinear and rate-dependent, both as a function of the displacement across the MR damper and the command current being supplied to the MR damper. As such, to develop control algorithms that take maximum advantage of...

2D Unit Cell Model

Rachelle Howell, Xiaoyue Wang & Ellen M. Rathje
This OpenSees model is a 2D plane strain model of the area of influence around a single drain (or, in the case of the untreated model, a free-field untreated area equal to the area of influence around a single drain). It was developed to simulate lateral spreading in the SSK01 and RNK01 centrifuge tests performed at UC Davis as part of the project NEES-GC: Seismic Risk Mitigation for Port Systems. The model consists of two...

Phenomenological Bouc-Wen Model for 200 kN Large-Scale Magneto-Rheological Fluid (MR) Damper

Anthony Friedman & Zhaoshuo Jiang
This is a Phenomological Bouc Wen model for 200 KN large-scale magneto-rheological fluid damper (a model of the PWM Servo-Amplifier used to drive the damper is also included) developed at the Purdue University. The physical counterpart of this model is the 200 kN large-scale MR dampers that are manufactured by the Lord Corporation. The damper is 1.47 m (58 inches) in length, weighs approximately 2.734 kN (615 lbs), and has an available stroke of 584...
