New Characterizing Method of a 3D Parametric Lattice Structure

Abstract

Engineering designers often adapt their design structure to the needs offunctional requirements independently of the capacity of the designedtechnical system to offer innovative capacities. Based on the notion ofcontradiction brought from TRIZ theory (Russian acronym for theory ofinventive problem solving), we have developed an approach to reverselybuild a parametric intelligent structure potentially solving a wide range ofinventive problematic situations. The proposed structure relies on anelastic buckling instability. A parametric CAD (Computer-Aided Design)model of the structure was carried out and its behavior is studied withfinite element analysis (FEA), driven by a design of experiments (DoE). Inthis article, a specific method of characterization and multi-objectiveoptimization of the structure is offered. Our objective is to bring a methodto allow an engineering designer to solve rapidly and inventively hiscontradictory requirement in adapting it to the industrial applicationsought for
