“…One of these models that has been used to describe MR dampers is the Dahl model [4] which consists of a first-order nonlinear differential equations that approximate experimentally observed hysteresis loops. It has been used in references [5][6][7][8][9][10][11] to describe the MR dampers behaviour.…”

SUMMARY Magnetorheological (MR) dampers are promising control devices in civil engineering structures as they combine reliability and stability of passive systems while maintaining versatility of active devices without large power requirements. These dampers are intrinsically nonlinear, so one of the challenging aspects of applying this technology is the development of accurate models to describe their behaviour for control design and evaluation purposes. This paper deals with the parametric identification of three large‐scale MR dampers which are modelled using the viscous + Dahl model. Experimental results show reasonably good agreement with the forces predicted by the identified models. Copyright © 2011 John Wiley & Sons, Ltd.

Summary Critical equipment and machinery, especially the one in the technology facilities, hospitals, data centers, etc., are vulnerable to strong earthquakes, and most importantly, the failure of the critical equipment will result in countless economic loss, directly and indirectly. For decades, passive control devices in the form of isolation systems between the equipment and its supporting structure have been acknowledged as an effective measure to promote the earthquake resistibility on the basis of theoretical and experimental results. Alternative to passive isolation systems, researchers found that adding a semiactive device to the isolation system can increase damping and lessen the isolator displacement. In order to mitigate the acceleration of equipment, various control algorithms have been developed to reduce the response produced by the internal forces. However, little attention has been given to the balance between the response of equipment and the structural response. In this study, an innovative control algorithm is developed based on decentralized control architecture and wavelet analysis, and this control algorithm is proposed for semiactive isolation systems to protect acceleration‐sensitive equipment against strong earthquakes. Subsequently, a full‐scale specimen is constructed; moreover, a curved surface slider (CSS) system with a magneto‐rheological (MR) damper are placed between the equipment and the floor to suppress the vibration. The experiment is conducted with a feedback control system to validate the performance and efficiency of proposed control algorithm. In the last place, the discussion and some conclusion are also drawn in this paper.

Chopped E-glass fiber-reinforced epoxy composites (10%, 30% and 50%) were fabricated and their mechanical and tribological behaviour was investigated. Three-point bending tests were performed according to the ASTMD790 and tensile tests were performed according to the ASTMD638 standards. Impact tests and hardness measurements of the composites were also carried out. Wear behaviour of composites was studied using pin on disc wear testing device. The design of experiments approach, using Taguchi method, was employed to analyze the results. Signalto-noise ratio and analysis of variance were used to determine the influence of parameters on the wear rate and coefficient of friction.
