US 2014/0372082 A1 · TOOL FOR OPTIMIZED THIN WALL PROFILE MEMBER (TPM) AND TPM-PANEL DESIGN AND SELECTION

Abstract

The present disclosure describes tools and associated computational analysis methodologies employed therein for improved TPM and TPM-panel weight-optimization and selection. The tools draw on inter-dependence parameters relating to TPM cross-section dimensions ratio values and established constructive restrictions to calculate, using appropriate algorithmic computational analysis, the optimum cross-section dimensions values of a given TPM. The proposed computational analysis is used in the selection of weight-optimized TPM-panels. A design selection serves as a blueprint for the next stage which is the actual fabrication or manufacturing of the component. For a given set of constructive restrictions, the final product is based on optimum configurations selected from a fixed set of TPMs with varied cross-sectional shapes; or in the case of TPM-panels, on optimum configurations selected from a fixed set of TPM-panel combinations of varied cross-section dimensions.
