Abstract: The eddy current damper has widespread application prospect in vibration control field which has advantages of non-contact and non-mechanical wear etc. A novel lateral eddy current damper was uesed for lateral vibration suppression of rotating disk. The electrical model of eddy current damper was established based on electromagnetic field theory, the radial and axial force of formulas were deduced combined with disc structure parameters. The relationship of the damping force and current, clearance(the distance between the end face of damper coil and disk) and the speed of disc was simulated and analyzed. The study laid a theoretical foundation for the implementation of vibration control and practical application of lateral eddy current damper.

Key words: Lateral Eddy Current Damper, damping force, rotating disk
