Vibration protection of devices sensitive to angular vibrations

AIP Conference Proceedings, 2020
Electronic devices installed inside moving objects may experience significant impulse and vibrational mechanical loads, causing combined translational and rotational vibrations in these devices. In this paper, we investigate the possibility for realizing passive vibration isolation of a vibration-protected block from angular vibrations provoked by the ...

Vibration protection for rotating machinery

Electrical Engineering, 1944
Vibration protection becomes desirable for rotating machinery when it is operated with certain defects. Electric generators may be operated with a single ``ground'' on the rotating field circuit without harm but the potential hazards of a second ``ground'' at another point on the same circuit are so great that the need of protective equipment for ...

Torsional Vibration Protection System

Volume 6: Structures and Dynamics, Parts A and B, 2011
The increasing use of variable frequency drives (VFDs) and island mode power generation due to remotely located sites make these Oil and Gas industry plants vulnerable to sub-synchronous torsional interactions. These interactions can occur with synchronous generators supplying island-like power systems with large VFDs, but also in synchronous motor ...

Vibrational Properties of Thiolate-Protected Gold Nanoclusters

Accounts of Chemical Research, 2018
Over recent years, the field of thiolate-protected gold nanoclusters has made remarkable progress. The successful determination of the structure of some of these clusters by X-ray crystallography was a milestone in this field. X-ray crystallography is arguably the most important technique in the field up to now, and it enabled the study of structure ...

VIBRATION PROTECTION OF SENSITIVE ELECTRONIC EQUIPMENT FROM HARSH HARMONIC VIBRATION

Journal of Sound and Vibration, 2000
Vibration protection of sensitive electronic equipment which operates in harsh environments often relies on resilient mounts. The traditional optimal design of vibration isolation from harmonic vibration is based on compromising damping and stiffness properties of mounts and is aimed, in general, at widening the frequency range over which the ...
