Vibration Testing

Vibration testing is performed by subjecting a product (test sample) to an excitation vibration input and monitoring its response. WESTEST regularly performs vibration testing using our multi-axial simulation table (MAST) system, vertical vibration table, horizontal vibration table, and electrodynamic shaker table. Vibration testing is used to evaluate how the test sample will respond to vibration inputs similar to that which it may experience during operation or transit and to verify the product is robust enough to survive the vibration inputs anticipated through its entire service life. In most cases, this is done by following test procedures defined by technical standards or through a customized client-specific test procedure. Some common vibration test standards for packaging and containers are listed below.

 

WESTEST’s vibration test equipment can be custom programmed for a range of vibration tests including sinusoidal, random, and actual field simulation tests using  RPC software . Our MAST system, vertical vibration table, and horizontal vibration table are all hydraulically controlled and are ideal for lower frequency applications (up to 100 Hz) and the electrodynamic shaker table is used for higher frequency vibration tests (up to 3,000 Hz).

 

Two of the more common vibration test applications we perform are sine sweep (resonance search) tests and vibration durability tests:

 

     

  • During sine sweep tests, the test sample is normally equipped with instrumentation to monitor its response at various locations while subjecting the sample to vibration inputs at discrete frequencies. The data collected during this test is primarily used to determine the natural frequencies of the test sample. Designers can use this natural frequency data to ensure their product does not exhibit natural frequencies in the range of vibration frequencies that are commonly experienced in service. If it does, a resonance condition will occur that amplifies the response of the product, often leading to premature failure. If this condition is detected prior to product release, the design can often be altered to shift the natural frequencies away from those commonly excited in service.

    Most commonly, vibration durability testing is conducted with sinusoidal, random, and field simulation inputs and is used to apply continual vibration inputs to the test sample to validate the long-term durability of a product when exposed to such vibration.
