They are the source of virtually all sinusoidal vibrations and waves.
2.
This can be sinusoidal vibration as used in ultrasound-assisted cutting or vibration noise, known as dither.
3.
The level of damping is demonstrated by the " quality factor ", Q which can also be thought of transmissibility in sinusoidal vibration case.
4.
Rayleigh stated the basic idea of reciprocity as a consequence of the linearity of propagation of small vibrations, light consisting of sinusoidal vibrations in a linear medium.
5.
Regardless of the vibratory signal studied ( sinusoidal vibration, shock, random or composite vibration ); the FDS can be obtained directly from the time history signal.
6.
The term'harmonic'comes from simple harmonic motion, and is equivalent to the'sinusoidal'concept described in the section below, thus " secondary harmonic " meant to describe the non-sinusoidal vibration caused by secondary imbalance is incorrect.
