On-Site Prediction of Overstress in an Aircraft Munitions Carrier

摘要

Vibration and strain data were measured on a modified munitions trailer to ensure that the design strength criteria had not been exceeded. These data were used in conjunction with a computer model to determine if the stress levels were sufficiently low to allow adequate fatigue life without further modification to the trailer. By combining standard data verification techniques with a stress prediction technique, data from a number of channels were reviewed at the test site to determine the severity of measured levels. This information was used to control the test process.
