Abstract

This paper presents a new magnetic suspension vibration absorber. In the hybrid magnetic configuration, two permanent magnets are embedded into a stationary base and a motion support to result in a spring effect in the mechanical system, together with introducing an electromagnet to exert controllable force onto the motion support. To achieve the expected characteristics, system design for this magnetic suspension system is discussed. The equation of motion is described and modeled by considering magnetic spring effect, aluminum eddy current effect and air breath effect to apply feedback control to the system performance. System identification and modeling are discussed. The design is revised using magnetic field simulation before fabrication. Implementation and experiment are presented to demonstrate this vibration absorber system performance. This system is established for further control studies and application investigations.
