An Evolutionary Computation Approach for the Electromagnetic Field Assessment of Eddy Current Motion Dampers

Abstract

Electromagnetic suspension and damper systems have recently emerged as valid alternatives to the traditionally utilized hydraulic systems. In the past, different analysis approaches were introduced for the performance assessment of active eddy current dampers and shock absorbers. This paper is to present an evolutionary approach for the solution of electromagnetic field problems related to permanent magnet eddy current dampers. The particle swarm optimization, which exploits simple analogues of social interactions, is utilized in the assessment of the permanent magnet eddy current damper forces. Details of the proposed approach and its numerical implementation are given in the paper. The obtained simulation results demonstrate the simplicity and computational efficiency of the proposed approach.
