Magneto-Rheological Elastomer based Smart Seismic and Vibration Isolators
- The project aims to develop Magneto-rheological elastomer (MRE) based base isolation systems as an adaptable smart base isolation system.
- The developed base isolation is adaptable, hence the large seismic gap demanded by the conventional seismic isolation can be controlled
- These isolators can be conveniently used in various ground excitations (near faults and far fault earthquakes), thus eliminating the need to design based on environmental conditions
- MREs are capable of adjusting their modulus or stiffness depending on the magnitude of the applied magnetic field. The isolated foundations supporting sensitive equipment that needs protection from incoming vibration and shock can be immensely benefited from the smartness of the MREs.
- Existing isolators for reducing the transmissibility of forces from machinery have been passive and are not adaptable. Conventional vibration isolators requires change in elastic properties and stiffness to cater to the changes in excitation frequencies. Use of MRE isolators shall ensure a constant isolation efficiency for a wide range of machine frequency excitations.
