Vibration Isolation and Chaotic Vibration
Volume 5: 19th Biennial Conference on Mechanical Vibration and Noise, Parts A, B, and C, 2003Taking single degree of freedom vibration isolation system under simple harmonic excitation as an example, and considering the energy, the vibration isolation performance in different conditions was studied theoretically and numerically. The results shows that when the simple harmonic excitation import energy is definite, the vibration isolation ...

Vibrator, vibration unit, and vibrator control method
The Journal of the Acoustical Society of America, 2006A vibrator has massaging balls supported by a treating unit that may be shifted along a subject portion for treatment, guided by guiding members. The treating unit is supported by a supporting structure with respect to the guiding members. A position or orientation altering mechanism is provided for altering the position of the treatment unit in a ...

Science, 1965
Itch produced by application of cowage to the wrist was reduced in intensity by vibration of the stimulated area. Application of vibration to the opposite wrist also reduced intensity. The results may be attributed to physiological activities occurring at the early stages of information transmission.

An Investigation of the Vibrations of Plates Vibrated at the Centre
Science, 1880Most of the plates used were window panes of various shapes and sizes, they were vibrated by rubbing an attached glass rod. The tubes, which were about-ji of an inch in diameter and 20 inches long, were attached at right angles to the face of the plate with sealing wax.

Vibration and Vibration Control
1990Vibration in machinery and structures is caused by the disturbing forces from, for example, reciprocating masses, unbalanced rotating masses, variable fluid pressure in hydraulic systems, turbulent wind loadings, wave action on structures, ground effects on vehicles, etc.
