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

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

MATHEMATICAL ANALYSIS OF HYDROPNEUMATIC SUSPENSION SYSTEMS
Abstract:
Every one of us might have seen the heavy trucks running on the roads. These vehicles have efforts on their axles very close to the allowed limits, mainly driving on rough roads or during cornering. In this case, the use of conventional suspension systems like those using McPherson Struts, Multi Link Suspension, Trailing Arm Suspension, 4- bar suspension etc. can increase the axle s overload phenomena. Hydropneumatic suspension ....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

One fundamental property underlines most biological databanks; their availability in text format Report gives an approach to retrieve and convert biological data stored in textual flat files into information in formats more suitable for further analysis and use by client applications. Extracted data can be exported into different data structures (CORBA objects, DBMS, C structures, HTML reports). These data structures are loader objects. They are generated based on loader specifications, which specify how to get specific pieces of information an ....etc
