Multi-Physical Analysis of Eddy Current Damper (ECD) for Reaction Force Compensation Device

This paper present multi-physical transient analysis of eddy current damper (ECD) for reaction force compensation device. A reaction force compensation mechanism with a movable magnet track and an ECD (or conductor plate) is developed. Lumped model of the ECD is derived and effects of both the location and width of the conductor plate are discussed. Multi-physical transient analysis of ECD is analyzed using commercial finite element software, which is compared with the lumped parameter analysis.
