Development of magnetic levitation device for active vibration control

摘要

In this paper, a novel active vibration control method for house structure by using magnetic levitation (MAGLEV) is proposed. Instead of active mass damper (AMD), a MAGLEV device is developed to provide the force for reducing the vibration from the wind or transportation. When a vibration occurs, the developed MAGLEV device will repeat to levitate and contact to the ceiling of housing properly. According to this movement, frictional force will be generated and used to reduce the vibration. For making the energy consumed by the frictional force maximum, optimum normal force which is provided by MAGLEV device is calculated. By using the proposed active vibration control method, simulation results are shown to verify its effectiveness.
