Document Type and Number:
WIPO Patent Application WO/2019/123792
Kind Code:
A1
Abstract:
The objective of the present invention is to improve the accuracy of an analytical service life evaluation. A service life evaluating device 1 comprises: a first service life evaluating unit (32) which obtains a first service life evaluation result by performing a service life evaluation using actual machine inspection data of a plurality of evaluation parts of a target member; a second service life evaluating unit (33) which obtains a second service life evaluation result by performing an analytical service life evaluation of the plurality of evaluation parts using standard material strength data of the target member; and an equivalent strength data creating unit (34) which, for each evaluation part, calculates, as unique strength data, strength data yielding a second service life evaluation result such that the difference from the first service life evaluation result lies within a prescribed permissible range, and which uses the calculated unique strength data of each evaluation part to create equivalent strength data of the target member.
