Abstract
In this study, when air mobility with a completed airframe assembly moves to its operational destination throughland transportation, such as trucks, the random vibrations generated during the transportation process are transmittedto the airframe structure, and the effect on the deterioration of the structural performance of airframe parts isanalyzed. To study the impact of ground vibrations on the structure, the random vibration test conditions defined inMIL-STD-810H Method 514.8, the U.S. military environmental testing standard, were applied to investigate thestructural integrity; the strength standards assumed in previous studies were the same. We present a design plan thatensures structural integrity while ensuring the continuity of the research results.
