ABSTRACT:
The present invention aims at estimating a residual life of a blasting vessel. For the estimation, a strain gauge30is attached to a blasting vessel10. The strain gauge30measures high-frequency repetitive strain caused in the blasting chamber10in each explosion. Strain waveform data obtained with the strain gauge30is analyzed to calculate the cumulative degree of fatigue damage due to a high-frequency repetitive load applied to the blasting vessel10in each explosion. A residual life of the blasting vessel10is estimated on the basis of a cumulative value of the cumulative degrees of fatigue damage.
