  • Resonance | vibration | Britannica

    Resonance in electrical systems is of a somewhat different nature. Its occurrence in frequency-sensitive (alternating-current) circuits makes it possible for communication devices equipped with such circuits to accept signals of certain frequencies while rejecting others. In a television receiver, for example,...

  • Measuring Vibration (br0094)

    The vibration amplitude, which is the characteristic which describes the severity of the vibration, can be qu- antified in several ways. On the diagram, the relation- ship between the peak-to-peak level, the peak level, the average level and the RMS level of a sinewave is shown.

  • A Brief Tutorial on Machine Vibration

    symptoms of natural vibrations, or resonance, are: 1. The vibration is very bad, in other words, abnormally high amplitude. 2. The vibration is strongly directional. 3. The amplitude is not steady, but varies up and down. 4. Rumbles during runup or coastdown as harmonics pass through the natural frequency.
