Abstract:
The first objective of this study was to determine and compare the fatigue damage from two different vibration events versus the fatigue damage from an envelope of both events. The second objective was to determine and compare the fatigue damage from the equipment test versus the fatigue damage from a section test while using the same vibration envelope. Both objectives were accomplished using NASTRAN models to calculate internal loads for use in the fatigue analysis. This study proved that the vibration envelope produced three times more fatigue damage than the worst vibration event, and two times more fatigue damage than both events applied sequentially. When the same vibration envelope was used in an equipment test and a section test, the analytical results showed the internal loads were quite different. Furthermore, this study demonstrated the need to validate and update analytical models with actual test data to derive accurate equipment loads.
