 note = {浮動型１自由度積分ジャイロに加速度を作用させたときに発生する誤差をジンバルの弾性モデルによって理論的に解析し，実験結果と比較・検討した結果，その誤差は定常加速度に関しては加速度の自乗に比例する特性を有することが，振動加速度に関してはジャイロの入力軸，スピン軸方向の剛性の相違（不等弾性）による固有共振周波数の差のために，ある周波数領域で異常に大きな値を有することがそれぞれ解明された。理論式の誘導，シミュレーション，タンブリングテスト，振動実験の結果からジャイロの誤差要因を分析し，かつジャイロの誤差評価を行なった。これにより定常，振動加速度による誤差は共にジャイロマークのベアリングを含むジンバル系の不等弾性に起因することが理論的，実験的に結論づけられた。, A floated single-degree-of-freedom integrating (SDF) gyro is used to sense angular rates  of vehicle motion, but senses the errors called "drift rates" by applying the acceleration whose direction is perpendicular to its output axis. The drift rate, which is proportional to the square of acceleration magnitude, is caused by a difference in compliance of the gimbal between the input axis and the output axis, and is called "anisoelastic error". In this paper, the anisoelastic error was analyzed theoretically and experimenta11y through derivation of the theoretical formula, tumbling test, vibration experiment and simulation. When vibrational accelerations were applied to the gyro, the anisoelastic error grew remarkably over a certain frequency range because of a difference in natural resonant frequency depending on the anisoelasticity, and was the same as that caused by steady acceleration at the frequency without the influence of natural resonance. The experimental results of the anisoelastic error were closely proportional to the square of acceleration magnitude and their frequency characteristics showed a tendency similar to the simulations., 資料番号: NALTR0188T000, レポート番号: NAL TR-188T},
