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

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
