Essentially all material will experience vibration, whether during manufacture, transportation, maintenance, or operational use. Vibration tests are performed to ensure materials and products will withstand the vibration exposures and synergistic effects of other environmental factors during a life cycle.
Vibration occurs on all forms of transportation and at varying levels of intensity in the in-use environment. 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. Some typical symptoms of vibration-induced problems are:
- 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
