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., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1930001000, レポート番号: JAXA-RR-19-001}, title = {風洞試験用内挿式六分力天秤の簡易設計手法}, year = {2019} }
