Define vibration. vibration synonyms, vibration pronunciation, vibration translation, English dictionary definition of vibration. n. 1. a. The act of vibrating. b. The condition of being vibrated. 2. Physics a. A rapid linear motion of a particle or of a
Another way to determine the order is analysis of the Campbell diagram. A good example of this can be seen in Figure 3. The example clearly shows vibrations occurring in the place where the order line crosses the mode line. The test turbine had 14 nozzles, causing this order of vibration...
C stretching bands occur between 1680 and 1600cm−1. In IR this results in a narrow, weak absorption band. Conjugation with another double bond lowers the frequency and often increases theIR bandintensity. Imino (C N) stretching vibrations result in strong Raman and moderately strongIR bands....
The device has noise units (5,7) shifted in oscillation with one another through in-contact stepping and/or third unit. The noise units are arranged for delivery of acoustic vibrations of different frequencies. A rotatable container (1) is provided to receive the noise units, and a crank is...
Another example could come from those who will leverage digital postprocessing techniques to remove the ripple over the frequency ranges that they are most interested in. In these cases, the repeatability and stability of the response is often more important than the flatness of the response over ...

Ground vibration due to blasting is identified as a challenging issue in mining and civil activities. Peak particle velocity (PPV) is one of the blasting undesirable consequences, which is resulted during emission of vibration in blasted bench. This stud
To determine the dynamic noise of an SPM the probe and sample are displaced in relation to one another (line or area scan). In this case, scan speed, scan range and measurement rate should be set to values typical of the subsequent measurements to be carried out. Usually the dynamic noise...
Microvibration induced by natural disturbance and human activities has an adverse effect on the operation of the large-scale and ultraprecise facilities in the world. Under such circumstances, a passive vibration control method is generally deployed for
