  • Why is Vibration Amplitude in G?Precision Microdrives

    Its true, we provide a Typical Normalised Vibration Amplitude. This means our acceleration measurements are adjusted to reflect the resulting vibration amplitude for a 100g mass it makes for easy comparison between different models. We could calculate normalised ratings for force and displacement, including the rated frequency.

  • Molecular vibrationWikipedia

    A molecular vibration occurs when atoms in a molecule are in periodic motion while the molecule as a whole has constant translational and rotational motion. The frequency of the periodic motion is known as a vibration frequency, and the typical frequencies of molecular vibrations range from less than 10 13 to approximately 10 14 Hz
