This paper describes the optimization and the performance evaluation of a Permanent Magnet spring. A dedicated semi-analytical model of the device is developed allowing for fast and accurate evaluation of the force vs. displacement characteristic of an arbitrary arrangement of coaxial ring-shaped PMs. This model is used to define the cost function to find the optimal PMs configuration which realizes a magnetic spring with a given characteristic. A stochastic, evolutionary, global optimization algorithm, based on a modified version of the self-organizing map is used. Once the optimal configuration is defined, the electromagnetic damping obtained by properly positioned conductive materials, will be investigated.

Abstract

This paper describes the optimization and the performance evaluation of a Permanent Magnet spring. A dedicated semi-analytical model of the device is developed allowing for fast and accurate evaluation of the force vs. displacement characteristic of an arbitrary arrangement of coaxial ring-shaped PMs. This model is used to define the cost function to find the optimal PMs configuration which realizes a magnetic spring with a given characteristic. A stochastic, evolutionary, global optimization algorithm, based on a modified version of the self-organizing map is used. Once the optimal configuration is defined, the electromagnetic damping obtained by properly positioned conductive materials, will be investigated.
