PRELIMINARY DESIGN OF WINGS Volume Ⅲ – Minimum Weight Design of Stiffened Plate

摘要

A design philosophy based upon mathematical logic and structural behavior is developed to obtain the minimum weight design of determinate structures. The philosophy is applied to stiffened skin constructions to obtain a nondimensional minimum weight design procedure and digital program which are readily applicable to any material, temperature, loading, thickness, stiffener spacing or height. Techniques for improving the efficiency by choice of stiffener and material are also presented. The assumptions utilized to analyze and design the structure are reviewed, and their effect upon the weight and margin of safety of the design is assessed.
