MAGNETORHEOLOGICAL FLUID DAMPER
1.INTRODUCTION
Vibration isolators or dampers are commonly used to mitigate vibrations in structures or machines. The isolators are typically passive and they are designed to reduce the vibration of the most undesired frequency. However, in many applications, the excitation frequency varies across a large range. In a semi-active device, the stiffness or damping can be adjusted during operation. Changing the stiffness of the support device can be exploited by moving the eigenfrequency of t ....etc

Introduction
Agitated friction welding (FSW) is a solid state bonding process that uses a non-consumable tool to join two work pieces that face without melting the workpiece material. The heat is generated by friction between the rotating tool and the workpiece material, which leads to a smoothed region near the FSW tool. While the tool is traversed along the joining line, it mechanically intermixes the two pieces of metal, and forges the hot and smoothed metal by the mechanical pressure, which is applied by the tool, as well as joini ....etc

Abstract

In paper the fundamental question about optimal interaction between the controlling stimuli generated by the active (powered) and the passive (unpowered) drives of the robotic systems have been studied. A mathematical statement of the problem has been proposed that is suitable to study this question for the semi-passively actuated n-degree-of-freedom robotic systems. The problem is formulated as an optimal control problem for n-degree-of-freedom mechanical system models a semi-passively actuated robot. We take into account the inter ....etc

Evaluation of Active Damping for Reduction of Noise, Vibration and
Motion of Ground Vehicles
The off-road vehicles are subject to large vibrations which can have severe affects on drivers, crew and load.Most ground vehicles are equipped with passive spring and damping devices which have reached a high
level of sophistication.active damping, has reached production stage for luxury vehicles, trucks and trains.

Studies by Karnopp for automotive applications suggest that the efficiency of semi-active dampers is only marginally low ....etc

Abstract:
A modified friction damper is presented to enhance the performance of conventional friction damper and semi-active variable friction damper. An additional plate is provided between the two sliding plates of a conventional friction damper which results in an additional sliding interface with the same normal (clamping) force. Similar modification is also made to semi-active variable friction damper (SAVFD) to enhance its performance. The enhancement in the performance of the benchmark building is studied under across wind loads ....etc
