...Y. Yun; Y. Li In recent years, many applications in precision engineering require a careful isolation of the instrument from the vibration sources by adopting active vibration isolation system to achieve a very low remaining vibration level, especially for the very low frequency under 10 Hz...

...H. Porumamilla; A. G. Kelkar; J. M. Vogel This paper presents a novel concept in active pneumatic vibration isolation. The novelty in the concept is in utilizing an air-spring-orifice-accumulator combination to vary the natural frequency as well as inject damping into the system per requirement...

... engineering damping vibration isolation optimal control feedback 17 12 2004 01 08 2006 Among the advantages of a variable stiffness device for extracting energy from the structure, as opposed to damping devices, is that in cases of shock loading, large forces are not transmitted...

...Alok Joshi; Won-jong Kim A mathematical model of a six-degree-of-freedom (6-DOF) hexapod system for vibration isolation was derived in the discrete-time domain on the basis of the experimental data obtained from a satellite. Using a Box–Jenkins model structure, the transfer functions between six...

... applications of this maglev stage include manufacture of nanoscale structures, atomic-level manipulation, assembly and packaging of microparts, vibration isolation for delicate instruments, and seismic motion detection.

...Yisheng Zhang; Andrew Alleyne This paper describes a novel reformulation of a classical active vibration isolation problem, explicitly accounting for the dynamics of the actuator. By utilizing a clever reformulation of the problem rather than the traditional approaches, a very difficult problem can...

... deflection and vibration isolation. The next level, passive hydraulic mounts can provide a better performance than elastomeric mounts especially in the low frequency range. Subsequently, semi-active and active techniques are used to improve performance of hydraulic mounts by making them more tunable...
