 note = {アニュラ型ニューテーションダンパの減衰特性を,3自由度球形エアベリング試験台を用いて測定した.直径254mm,水銀封入量120g程度のダンパを,重量約50kg,マスレシオ1.35の衛星モデルに取付けた場合,スピン速度約2rpsのとき,初期ニューテーション角約5度のニューテーションは,約10秒程度で減衰することが確認された.空気抵抗のニューテーション減衰効果を,ダンパ無作動時の測定結果を用いて近似的に補正すれば,減衰に関する理論値と実験結果は比較的よく一致することが明らかになった., This report presents the results of an experiment to measure the damping rate of an annular nutation damper used to damp out the nutational motion of an artificial satellite. The experiment was performed by mounting the damper on a model satellite, which in turn was supported by a spherical air-bearing test stand. The annulus of the damper had the diameter of 254 mm and was filled with mercury to about one-sixth of its volume. The model satellite had a mass ratio of 1.35 and weighed about 50 kg. The initial nutation angle of about 5 degrees was observed to damp out within a matter of 10 seconds, when the spin rate was approximately 2 rps. The measured damping rate was found to agree comparatively well with the theoretical one after the effect of air resistance was excluded by using the experimental data obtained without the damper., 資料番号: SA0125272000},
