Optimized bolted joint

摘要

A joint for joining composite material such as segments of the skin 12 and 13 of an aircraft. Tapered splice plates 30 and 31 overlap the ends 14 and 15 of the skin. The thickest portion 34 of the splice plates overlap the ends 14 and 15. The splice plates are clamped together on the skin segments 12 and 13 by fasteners 50, 52, 54 and 56. The tapered splice plates are designed to minimize load transfer at the outermost bolt row 56 coincident with maximum bypass stress in the skin segments while simultaneously maximizing load transfer in both the skin segments and splice plates at the innermost bolt row 50.
