Abstract
Description
本発明は、少なくとも第1の所定の力の作用下における弾性的な構成部材の最終的な目標形状を予め設定しながら、弾性的な構成部材特にヒンジのないワイパアームの未加工素材形状を規定するための方法に関する。
弾性的な構成部材の形状は、簡単な3次元的なモジュール(その変形が簡単な力の場の影響によってその限界値において分析的に計算可能である)によって概算される。有限要素法の概要は、教科書「" Finate-Elemente-Methoden " von Klaus-Juergen Bath, erschienen im Springe - Verlag Berlin-Heidelberug Im Dezember 2001 (クラウス・ユルゲン・バース著の”有限要素法”、シュプリンガー出版社、ベルリン−ハイデルベルグ、2001年12月」に記載されている。
図2は、ワイパアームの作業モジュールの平面図、
図3は、図2に示したモデル未加工素材形状の作業モジュールに対抗力を加えた状態の概略図、 図4は、ヒンジのないワイパアームの未加工素材形状に押し付け力を作用させた状態を示す概略図、
図5は、本発明による方法のテスト段階を示す概略図、
図6は、作業モジュールを有限要素に分割する状態を示す概略図、
図7は、長手方向力の作用下で有限要素を変形する状態を示す概略図、
図8は、横方向力の作用下で有限要素を変形する状態を示す概略図、
図9は、曲げモーメントの作用下で有限要素を変形する状態を示す概略図、
図10は、図1〜図9に示した作業モジュールの有限要素の変形全体の領域を示す概略図である。
δYi=Fqili 3/(3IiE)+Mili 2/(2IiE)
δXi=Flili/(AiE)
この場合、シフトδXi及びδYiは、横軸が、箇所Viにおける作業モジュール12の曲げ曲線の延在方向に対して接線方向に延びている座標系に関連している。以上の式から、新たな角度φi=φi−1+δφiと、次の座標を有する新たな重心点Vi″′が得られる。
及び
Yi″=Yi″+cos(φi)δYi′−sin(φi)δXi′
誘導段階を終了させるために、角度変化δφiと弾性的なシフトδXi=Xi″′−Xi、及びδYi=Yi″′−Yiが、次の有限要素Ei+1に対する角度の計算並びに座標の計算に利用される。
