Abstract風洞試験用内挿式六分力天秤の設計を材料力学の基本知識のみで行える簡易手法を開発した.航空機形状模型に対する風洞試験で使用される天秤は,作用する垂直力が大きく軸力が小さいため複雑な形状にならざるを得ず,そのため確立された設計法も無く,天秤メーカの経験に頼ってきたのが現状である.本稿では,各検出部の応力およびひずみを材料力学の基本式のみから闇単に手計算で推測できる手法を公開し,汎用の構造解析ソフトウエアによる計算結果との比較,さらにはJAXA複合荷重式自動天秤較正装置での較正結果も合わせて紹介する.
A simple design method of internal six-component balances for wind tunnel testing with elementary knowledge about material mechanics has been developed. Because relatively large normal force and relatively small axial force act simultaneously on balances for aircraft models in wind tunnel testing, the balances must have complex structure. No design method has been established because of the complexity, and we have therefore depended on the experience of balance manufacturers. This article describes a simple calculation method of stress and strain of balance elements using fundamental equations of material mechanics, comparison between calculation results by the method and those by general-purpose structural calculation software, and furthermore, calibration results for a balance designed by this method using the JAXA automatic balance calibration machine.
