Vibration evaluation method for rotary body in static field |
摘要 |
<p>A method of evaluating the vibration of a rotary body in a static field to determine a profile of a critical speed and a profile thereof in a region exceeding a rated revolution velocity of the rotary body. This method comprises maintaining the rotary body by bearings in a non-rotating condition; providing a rotary vibrator for applying a rotational exciting force to the rotary body, a vibration sensor for detecting the vibration of the rotary body, and a vibration meter for measuring an output from the vibration sensor; and measuring a vibrational response of the rotary body by sweeping a rotational frequency of the rotational exciting force applied from the rotary vibrator to the rotary body. Thus the vibrational characteristics of the rotary body in a simulated rotational field are obtained. <IMAGE></p> |
