One illustration utilizes the second example, where relative motion between a model structure and a shaking table is measured by digitally processing the analogue image provided by a video tape recorded during a shaking table test of a model structure base isolated by a hybrid isolation device consisting of friction and elastomeric components.
Furthermore, an integrated isolation device is proposed that consists of the periodic isolator and a dynamic absorber, and its isolation performance is investigated.
A solid hours work produced The Depravator, an advanced sensory isolation device made from an old welder's helmet with a blacked out visor, two sets of plugs (nose and ears), and a pair of thick, woolen mittens (touch).
To this purpose, in the paper one deepens some theoretical and practical features relevant to the problem of properly approaching the design of a base isolation device.
It is based on an industrial vibration isolation device and exhibits many of the same anti-windup design challenges that were described in [24].
Therefore, the role of the base isolation device isolating the superstructure from the ground motion does not perform properly, which causes amplification of the floor response of the superstructure.
In this paper, a soft active isolator (SAI) derived from a voice coil motor is studied to determine its abilities as a micro-vibration isolation device for sensitive satellite payloads.
Then, the anti-windup technique is tested on a simulation example and finally shown to perform excellently on a commercial vibration isolation device: Newport Corporation's Elite 3TM active vibration isolation system which has been patented and is now commercialized with this architecture.
In an animal model of focal cerebral ischemia, cells isolated with the HuriCell isolation device showed neuroprotective effects in ischemic brain injury [ 117].
The findings can serve as a practical guide for isolation device designs where the uncertainties with ground motions and variability of structural properties are effectively incorporated under the fragility function framework.
