回転体における動的姿勢変化時の振動特性の評価

抄録

The small fan motor is used now to cool off with the IT apparatuses including the personal computer. An examiner evaluates a sound and vibration by the quality check of the small fan motor, an examiner changes the posture of the small fan motor dynamically. As for this method , an effect is recognized from experience in inspecting quality, but because the effect is not clear theoretically, an elucidation is necessary. Therefore I clarify a principle of rocking it using an experimental device and multibody to change the posture of the body of rotation consecutively in this study.
