Summary

This study investigates the causes of cracks occurring in aircraft bulkhead fastening structures during operation and proposes improvement measures. The cracks are found to be caused by fatigue failure due to repeated loads, with gaps resulting from assembly tolerances and reduced pre-load identified as major contributing factors. The improved design, achieved through structural reinforcement and gap removal, demonstrates sufficient structural safety and a significantly extended service life.
