• 論文の詳細を見る

• This paper deals theoretically and experimentally with a nonlinear forced oscillation at a major critical speed in a rotating shaft which is initially bent. When an unsymmetrical shaft carrying a disc or a round shaft (a shaft with circular cross section) carrying an unsymmetrical rotor has an initial bend, and when it is supported by singlerow deep groove ball bearings having angular clearances, its nonlinear spring characteristic fluctuates with rotation of the shaft due to the initial bend. In such a rotating shaft system, there appears a nonlinear restoring force rotating with the shaft. The resonance curves at the major critical speed in this system are more complicated in shape than those in a straight shaft system and their shapes vary with the angular position of the rotor unbalance.
