Abstract
Description
−ケーシング内でインペラを回転させるステップと、
−導電体の端子で、ケーシングに対向するベーンの先端に含まれる磁石によって誘導される電圧を測定するステップと、
−測定電圧からベーンの先端が受ける振動を表す情報を決定するステップと、
を含む。
図3は、磁石3を備えるベーン20が受ける振動を特徴付ける方法のステップを示した図である。
図4を参照すると、固定フレームRはケーシング1に関連付けられ、可動フレームR’は磁石3に関連付けられる。
磁石3が巻き開口部46に対向し、導電体4が磁石3の磁場Bの影響から逃れる場合、当然、誘導電流を発生させる現象が生じる。
中心部40の端子で記録された電圧の時間信号s(t)は、インペラ2の回転軸z’に平行なベーン20の振動速度成分の直接画像である。
ステップ104で得られた図7に示されている信号s(t)に対応するスペクトルS(f)は、以下の形で表される。
−全体の原動機次数は、ディラックの櫛形関数によって、周波数が速度に同期するスペクトルにおいて明確に実現される。
導電体4は、インペラ2に対向するケーシング1の内側面10に直接位置決めされる。
