Negative-Stiffness
6Pages

Why Negative-Stiffness is better Negative-stiffness isolators provide a simple, reliable and highly effective isolation solution for sensitive instruments at the low frequencies and amplitudes of floor and building vibrations. They are passive, relatively small, light weight, stable, and cost-effective. The isolators are easy to use and adjust. They can be more economical than air systems, take up less space, provide better isolation at very low vibration amplitudes, and require no air, electricity or maintenance. SUPERIOR VIBRATION ISOLATION Applications Audio • Audio reproduction • High End Audio How they work Minus K negative-stiffness isolators are completely mechanical. Isolation is achieved using an arrangement of springs and negative-stiffness mechanisms. These systems provide isolation in six degrees of freedom with resonant frequencies as low as 0.5 Hz or lower. The result is a compact passive isolator capable of very low vertical and horizontal natural frequencies and very high internal structural frequencies. Biology/Neuroscience • Electrophysiology measurements • Fluorescent dye imaging • Patch clamping • TIRFM: Total Internal Reflection Fluorescence Microscopy Electron Microscopes • SEM: Scanning Electron Microscope • TEM: Transmission Electron Microscope • STEM: Scanning Transmission Electron Microscope Microelectronics/MEMS Fabrication Other advantages Multiple isolators can be used together while still acting as one with respect to vibration, which allows great versatility in designing for a range of applications. Minus k’s negative-stiffness technology has successfully isolated sensitive instruments that range from a few pounds to thousands of pounds. Isolators can be adapted for Cleanroom or Vacuum environments.

Minus K isolators (adjusted to 0.5 Hz) achieve 93% isolation efficiency at 2 Hz, 99% at 5 Hz, and 99.7% at 15 Hz. Isolation performance closely follows that of an ideal undamped single DOF (Degrees Of Freedom) system up to about 10 Hz and reaches a floor in the transmissibility curve with some resonances at the higher frequencies. High-Performance Air With Vibration Isolation Spacecraft Ground Testing OEM Suppliers to many of the world’s leading manufacturers of SPMs, micro hardness testers and inferometers Minus K® vibration isolation systems deliver 10x to 100x better performance than high-performance air systems and even better than active systems.
