OSCILLATION EVALUATION DEVICE AND EVALUATION METHOD
摘要
<p>An oscillation evaluation device includes a plurality of sensors (a distortion gauge, an acceleration meter, an ultrasonic wave sensor) which measure data on oscillation at a plurality of measurement points of a jet pump; an oscillation analysis unit which performs oscillation analysis by using a numeric value structure analysis model of the jet pump and obtains an oscillation state of the jet pump; and an evaluation unit which estimates and evaluates the oscillation state at each of the positions of the jet pump by using the numeric value structure analysis model when the analysis result at a position corresponding to the measurement point of the oscillation analysis by the oscillation analysis unit coincides with the measurement data obtained by the sensor.</p>
