Tag: Sinusoidal Vibration Testing

A vibration resonance occurs when equipment or a product is exposed to an external forced vibration occurring at one or more of its natural frequencies.  The resulting product response vibration is amplified and can be huge!  Vibration resonances can cause severe damage to products and significantly shorten their life.  Examples of vibration resonances can be seen below and in our video page.

A 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.

Sinusoidal or Sine Vibration Testing is one of the more common types of vibration testing services performed by vibration test labs. See Sinusoidal Vibration Basics to learn more about vibration fundamentals. A primer containing a more technical explanation on sinusoidal vibration testing can be found in our blog article Sinusoidal and Random Vibration Testing Primer. The types of Sinusoidal Vibration Testing are Sine Sweep Vibration Testing, Sine Dwell Vibration Testing, and Sine-on-Random Vibration Testing.
