Anti-vibration mount for vibration-sensitive applications

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.

Potential benefits

  • 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)
  • Versatile:
    • Able to perform at any angle
    • Size can be customised
  • Low-cost:
    • 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

Potential applications

  • Industrial manufacturing
  • Electronics
  • Aerospace & Defence
  • Research (astronomy)
  • Laser and optical systems
  • Microscopy and medical imaging
