Abstract
Vibrations are induced due to continuous working of machines in industries or due to earthquake motion which are transmitted to the adjacent structural elements. These vibrations must be controlled in order to reduce its transmission. An experimental model is developed using permanent magnets for isolation of system from the vibrations. Airgap between the permanent magnets is obtained by applying loads of 20 and 30 gm in each of magnetic arrangement. Airgap versus load-weight [1] plot for each case is given to understand the vibration in repulsion with magnetic arrangement. Airgap measured is found to reduce by 80% for arrangement of ring magnets and by 78% for arrangement of plate magnets compared to the airgap without any loading. The plate magnet shows higher value of magnetic field at lower loading than the ring type magnets. It is seen that in the SDOF system using spring and magnets, the displacement increases with increase in forcing frequency in all cases.
