Abstract

This paper proposes a new linear magnetic damper to absorb shock from the crash accident of high speed vehicles. The magnetic damper is composed of a copper plate, a yoke, and permanent magnets. The damping force is generated by the eddy current in the copper plate. Also, permanent magnets are aligned using Hallbach array to improve the damping force. Magnetic field analysis including thermal characteristics is performed by using J-MAG, commercial FEA tool, and the FEA results were validated by the experiment. Finally, the specification and the performance of the proposed magnetic damper are represented
