  • What is a Vibration Resonance?

    Jun 22, 2015A natural frequency is the frequency at which a system will oscillate after an external force is applied and then removed. All objects have a natural frequency at which they vibrate. Most products have many natural frequencies. During vibration testing using vibration shakers, a sinusoidal vibration resonance scan or resonance search is used to study resonances in products.

  • Resonance

    A structure will have a resonant frequency in each of its 3 directional planes (x, y and z, or as we call them, horizontal, vertical and axial). Resonance serves to amplify the vibration due to whatever vibration force is present at (or near) that resonant frequency. It is important to note that resonance does not cause vibration - it amplifies it.
