| 摘要 |
The present invention includes: a plurality of sensors (strain gauge, accelerometer, ultrasonic sensor) that measure data on vibration at a plurality of measurement points on a jet pump; a vibration analysis unit that performs vibration analysis using a numerical structure analysis model of the jet pump, and calculates a vibration state of the jet pump; and an evaluation unit that estimates and evaluates a vibration state in each position on the jet pump using the numerical structure analysis model when an analysis result in a position corresponding to the measurement point by the vibration analysis of the vibration analysis unit matches the data measured by the sensors. |
