MIL-STD-810: Vibration Testing Category 4 – Truck/Trailer – Secured Cargo

MIL-STD-810: Vibration Testing Category 9 – Aircraft – Helicopter

Category 7 of Method 514.7 Vibration testing simulates vibration conditions of cargo in jet aircraft.  These vibrations are broadband random.  Typically the maximum vibration levels produced are caused by the exhaust noise generated during takeoff.  Vibration during normal flight is substantially less.  Figure 1 and Table 1 detail the Acceleration Spectral Density (ASD) and frequency levels of various aircrafts and the vibration exposure of cargo carried on those respective aircrafts during takeoff.  The General Exposure curve can be used when the specific aircraft is no known.

The test duration is 1 minute per takeoff times the number of takeoffs the product may see in its lifetime.
