Researchers from The Australian National University have developed a system for isolating and suppressing the transmission of vibrations between a vibrating object and vibration-sensitive structures, such as astronomical instrumentation, laser and optical systems, microscopy and medical imaging, precision instrumentation in robotics, semiconductor manufacturing and many others. The system uses a novel design of negative-rate springs, which allows it to achieve extremely low natural frequencies, resulting in isolation that is orders-of-magnitude better than conventional springs and rubber isolators, can operate in gravity-varying environments, and at any angle. This low-cost and durable technology has the potential to provide unprecedented isolation solutions to advanced technologies and systems in electronics, aerospace, industrial manufacturing, defence and research.
- Novel: The first negative-stiffness isolator that can be used in a gravity varying (tipping) environment
- Effective: Able to achieve ultra-low natural frequencies (<1Hz)
- Able to perform at any angle
- Size can be customised
- Extended durability of components = less expensive operation
- Smaller components = smaller packaging and easier transportation
- Easy to manufacture
- Reliable: Decreased range of motion in "soft" sub-components (hoses, connectors) = prolonged durability and failure reduction
- Industrial manufacturing
- Aerospace & Defence
- Research (astronomy)
- Laser and optical systems
- Microscopy and medical imaging
ANU is seeking licensing opportunities for this technology, as well as engagement with prospective industry partners to work collaboratively with us on the prospective integration of the anti-vibration technology into other advanced technologies and systems.
