An Eddy current damper uses magnets to suppress vibrations due to external excitations. These dampers also called electromagnetic dampers, have advantages of no mechanical contact, high reliability and stability, but require a relatively large volume and mass to attain a given amount of damping. | Analysis of Eddy current damper for suppression of vibrations using COMSOL software Engineering Solid Mechanics 3 2015 215-222 Contents lists available at GrowingScience Engineering Solid Mechanics homepage www.GrowingScience.com esm Analysis of Eddy current damper for suppression of vibrations using COMSOL software Rajwinder Singh and V.P Singh Department of Mechanical Engineering 1. Pec University of Technology India ARTICLE INFO ABSTRACT Article history An Eddy current damper uses magnets to suppress vibrations due to external excitations. These Received 6 April 2015 dampers also called electromagnetic dampers have advantages of no mechanical contact high Accepted 20 July 2015 reliability and stability but require a relatively large volume and mass to attain a given amount Available online of damping. The magnets respond to an external excitation field. Along with the construction 21 July 2015 Keywords of the damper COMSOL software is used for analysis of the eddy current damper and got Eddy current damper various results like magnetic flux density eddy current intensity velocity and acceleration of Numerical analysis the moving magnet. For this a standard dimension of an automotive vehicle damper is used so AC DC Tool that the prototype could be tested on a damper testing machine. The standard dimension is COSMOL software chosen to increase the adaptability compatibility and to ease of testing the damper. After this task the response of damper under various loads is observed. Different materials of housing tube are taken to observe the effects of various parameters like flux density current intensity and of course the damping capability of the prototype damper. 2015 Growing Science Ltd.
