Variable Frequency Vibration Testing


Variable Frequency Vibration testing is performed to evaluate the ability of parts to withstand vibration of varying frequency within a specified frequency range. The variable frequency vibration test simulates withstanding moderate to severe vibration as a result of motion produced by transportation or field operation. Vibration of this type may disturb operating characteristics, particularly if the repetitive stress causes fatigue.

For design purposes, a swept frequency sinusoidal test may yield more pertinent design information such as resonant frequencies and modes than a random vibration test.  SCL is certified for variable frequency vibration testing uner mil std 202 method 201, mil std 750 method 2056, and mil std 883 method 2007.   IC variable frequency vibration testing is considered to be destructive.  SCL is also certified for Vibration Fatigue testing under mil std 750 method 2046.
