Vibration evaluating equipment and evaluating method

The invented vibration evaluating equipment contains: a plurality of sensors (strain guage, accelerometer, and supersonic sensor) used for measuring data related to the vibration at a plurality of measuring points on a jet pump; a vibration analysis unit used for analyzing vibrating condition of the jet pump using a numerical structure analysis model; and an evaluating unit, which applies the numerical structure analysis model to estimate and evaluate the vibration on each positions of the jet pump when the vibration at the measuring points calculated by the vibration analysis unit are consistent with the measured data of the sensors.
