A Prototypical Design of a Passive Magnetic Suspension System

Abstract

Suspension systems are continuously developed in the field of engineering to reduce mechanical vibrations. They are used to isolate delicate systems from vibrations to allow proper functioning and prevent damage. This article proposes an alternative suspension mechanism employing the repulsion forces between magnets with eddy current damping combined with air damping. No sealing is required in this system, so there is no risk of leakage. Calculations have been done to describe the damping characteristics of this suspension system. Static and dynamic tests are done on a prototype to justify the feasibility of this mechanism, obtaining a force-distance graph and transmissibility characteristics. Results suggest that this suspension system is very progressive compared to conventional suspension systems, but it provides a satisfying vibration reduction performance. The Magnetic Suspension System allows non-direct contact from the source of vibration to the detection end, providing rapid responses to shock. The Magnetic Suspension System is also not subjected to metal fatigue and is highly unlikely to undergo sudden failure.
