摘要： PROBLEM TO BE SOLVED: To provide a damage pattern discriminating method of a steam turbine by an AE signal capable of discriminating a damage pattern in a steam turbine, wherein damage of a turbine blade and seizure of a bearing can be discriminated at least.
SOLUTION: The damage pattern of a steam turbine is discriminated by using the correlation between the distribution and damage pattern of a waveform shape parameter s extracted from shapes W1, W2 of time sequential waveforms of an AE signal. The waveform shape parameter s is obtained by the ratio between effective amplitudes H1, H2 and durations T1, T2 of the waveforms. Moreover, the damage pattern can be discriminated by a waveform shape parameter integration S obtained by integrating the distribution of the waveform shape parameter s with respect to the waveform shape parameter s. The evaluation test of damage can be also carried out by correlation between the AE parameter value of a centroid frequency or the like based on the AE signal and the strength of the AE signal.

摘要： PROBLEM TO BE SOLVED: To provide a turbine blade thickness estimating method for estimating a thickness of a turbine blade of a steam turbine to be eroded. SOLUTION: While measuring an AE signal occurring by collision of particles flowing in liquid with a blade, particle diameter of a particle is obtained from a correlation between strength of the AE signal and a particle diameter. A spectral ratio R is acquired which is a ratio between an integration value S1 of components of low frequency ranges A1, B1 in a frequency spectrum of the AE signal and an integration value S2 of components of high frequency ranges A2, B2. The thickness is estimated from the correlation of the particle diameter of a particle, the thickness and the spectral ratio. The integration value S1 of the low frequency range component is an integration value preferably chosen from the whole A1 or a part B1 of the frequency range between 100 kHz and 400 kHz. The integration value S2 of the high frequency range component is an integration value preferably chosen from the whole A2 or a part B2 of the frequency range between 450 kHz and 600 kHz.

摘要： PROBLEM TO BE SOLVED: To provide a high-precision prediction method of a prodromal stage of rock destruction or the like supported by experiments. SOLUTION: An AE sensor is placed on a rock or the like. A prodromal stage is estimated by comparing a hybrid result of the first parameters d1 and E which are a plurality of parameters obtained from an AE waveform received by the AE sensor with an area of the prodromal stage which is obtained beforehand from the first parameters d1 and E. In addition, the prodromal stage is also estimated by the first parameter which is a rise time d1 which is a period from a point when the received AE waveform exceeds a certain threshold value Fa to a point when the waveform reaches the maximum value. Additionally, the prodromal stage is estimated by the first parameter which is obtained from an integrated value E of the received AE waveform during a certain period. COPYRIGHT: (C)2004,JPO
