HyperLifeで疲労強度検討をして航空機の認証（解析での妥当性証明）に使えますか？
Description: プロペラの構造物のハブの疲労強度 遠心力がフライト中かかっている。 空力荷重や振動がかかる。 これらの線形性解析結果ー応力と、それぞれの荷重履歴をインプットすればすべて考慮された疲労強度の解析結果は出ると思います。 これは、解析を基にした強度計算として認証向けに使えますでしょうか？ 認証活動としては最終的に実験検証で妥当性を証明することになりますが。強度計算書に使えるでしょうか？ 解析設定の妥当性は私の方で証明しなければいけませんが、HyperLifeはいかがでしょうか？ 実績がございますでしょうか？ Product/Topic Name : HyperLife、航空機構造、疲労強度 *Note from…
