PROBLEM TO BE SOLVED: To optimize structural topology of aircraft structural components in order to reduce the amount of material needed for building the structural components.SOLUTION: A method of designing a space frame involves; constructing a load stress map in a geometrical boundary representation of a design space; defining a plurality of attachment points and load application points; creating a starting network of interconnecting lines between each pair of the plurality of attachment points A and load application points L; assigning a load application factor to each line of the starting network of interconnecting lines based on values of the load stress map; generating a plurality of potential space frame designs by selectively culling different subsets of lines of the starting network of interconnecting lines for each potential space frame design according to variable culling parameters; evaluating a performance score of each of the plurality of potential space frame designs regarding predefined optimization parameters; combining the culling parameters for the potential space frame designs having performance scores above a predefined performance threshold; and iterating the steps of generation and evaluation of potential space frame designs on the basis of the combined culling parameters.SELECTED DRAWING: Figure 4

    【課題】構造要素を構築するのに必要な材料の量を減少させるために、航空機構造要素の構造トポロジーを最適化する。【解決手段】設計空間の幾何境界表現中に負荷応力マップを構築し、複数の取付け点及び負荷作用点を規定し、取付け点A及び負荷作用点Lのうち夫々2つの間に、相互接続ラインの開始ネットワークを作成し、負荷応力マップの値に基づき、相互接続ラインの開始ネットワークの各ラインに対して負荷適用因子を割り当て、可変の選別パラメータに従い、各立体骨組設計候補に対して相互接続ラインの開始ネットワークのラインの異なるサブセットを選択的に選別することで、立体骨組設計候補を生成し、所定の最適化パラメータに関し、立体骨組設計候補夫々の性能スコアを評価し、性能スコアが所定の性能閾値を上回っている立体骨組設計候補に関し、選別パラメータを組合せ、組合された選別パラメータに基づき、立体骨組設計候補の生成及び評価を繰り返す。【選択図】図4
