• 論文の詳細を見る

• The conditional equation of balance of a flexible rotor and the possibility of a new balancing procedure by aid of a mode separation network have previously been proposed by one of the authors. This paper deals with some experiments to verify the theory, where a variety of unbalance distributions is artificially given to a seven-disked flexible rotor which is supported by two flexible bearings and is balanced based on our theory. The bearing vibration together with dynamic shaft deflection after balancing is minimized over a wide range of rotational speeds as high as its third critical speed. Thus the theory is experimentally proved to be valid for balancing a flexible rotor.
