IMPACT VIBRATION CONTROL USING SEMI-ACTIVE DAMPER
Introduction
 Dynamic vibration absorbers are used for suppressing the steady state vibration of a machine.
 It consists of spring-mass-damper system.
 For an impact force, it can damp only the residual part of impact vibration
 But maximum amplitude of the vibration is almost remain same that of undamped vibration

ABSTRACT
Magneto rheological fluids commonly known as MR fluids are suspensions of solid in liquid whose properties changes drastically when exposed to magnetic field. Magnetorheological (MR) fluids are materials that respond to an applied field with a dramatic change in their rheological behavior. The essential characteristic of these fluids is their ability to reversibly change from a free-flowing, linear, viscous liquid to a semi-solid with controllable yield strength in milliseconds when exposed to a magnetic field. ....etc

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 o ....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
