Fatigue Strength of Lugs Containing Liners. Volume II. Computer Program Used for Analyses

摘要

The report presents the results of an investigation of the fatigue strength of structural lugs. Design charts were formulated for fatigue-loaded steel and titanium lugs containing interference fit liners. These lugs are representative of design practice in highly loaded aircraft applications, particularly that found in helicopter blade attaching systems. A primary element in the analytical study was a two-dimensional structural analysis of lug configurations. (Author)
