| Summary: | The present invention relates to a method for evaluating the fatigue limit and a device for evaluating the fatigue limit. The device for evaluating the fatigue limit comprises a peak coordinate value extraction unit used for extracting peak coordinate values containing a wave crest and a wave trough and existing in the surface distribution measurement values of a to-be-evaluated target part; an evaluation distribution data generating unit used for conducting the filtering treatment on the peak coordinate values of the wave crest or/and the wave trough so as to generate evaluation distribution data on the condition that the height difference between the wave crest and the wave trough adjacent to the wave crest is smaller than a predetermined threshold, wherein the height difference of the newly generated evaluation distribution data between the wave crest and the wave trough adjacent to the wave crest is larger than the predetermined threshold; a surface roughness index value calculating unit used for calculat |
