Military Vibration Testing


Essentially all products and materials will experience vibration, whether during manufacture, transportation, maintenance, or operational use. Vibration tests are performed to ensure products and materials will withstand these vibration exposures during their life cycle. Westpak performs Vibration Testing for Military clients per the applicable sections of MIL STD 810G. 

Vibration occurs at varying levels of intensity in the in-use environment and during all forms of transportation. Vibration results in dynamic deflections of and within material. These dynamic deflections and associated velocities and accelerations may cause or contribute to structural fatigue and mechanical wear of structures, assemblies, and parts. In addition, dynamic deflections may result in impacting of elements and/or disruption of function. 

Typical Procedures/Protocols
MIL-STD-810G

For Military applications, these symptoms of vibration-induced problems can lead to severe losses:

  • Chafed wiring
  • Loose fasteners/components
  • Intermittent electrical contacts
  • Electrical shorts
  • Deformed seals
  • Failed components
  • Optical or mechanical misalignment
  • Cracked and/or broken structures
  • Migration of particles and failed components
  • Particles and failed components lodged in circuitry or mechanisms
  • Excessive electrical noise
  • Fretting corrosion in bearings
