Semi-Active Magnetorheological Seismic Isolators
- Technology Benefits
- Unlike passive isolators, semi-active isolators have shown to use less energy and may be powered by batteries. Traditional semi-active isolators utilize fluids and they take up more space.
- Technology Application
- These novel isolators may be used to reduce seismic damage in building and bridges.
- Detailed Technology Description
- Researchers at the University of California, Irvine have developed a novel semi-active magnetorheological seismic isolator. This new isolator is composed of magnetorheological nanocomposites embedded between two steel plates. The magnetorheological nanocomposites incorporate multi-walled carbon nanotubes which enhances the performance of the isolator. Two steel yoke supports two coils which may be controlled to generate a magnetic field to change the stiffness of the magnetorheological nanocomposites. During an earthquake, sensors activate the semi-active isolators to adjust their stiffness to isolate the building or bridge in which it is embedded.
