Fatigue life equivalent prediction method and device of stressed part and computer equipment

Abstract

The invention relates to a fatigue life equivalent prediction method and device of a stressed part and computer equipment. A target finite element model of the stressed part is established by adopting a model establishment mode which is established in advance according to an experiment result of an impact fatigue sample; and performing fatigue life prediction processing on the target finite element model by adopting a predetermined life prediction mode to obtain a part life prediction result of the stressed part. According to the method, the actual part fatigue life experiment is simulated in a mode of combining finite element simulation and experimental measurement, so that the prediction time is shortened and the labor cost is reduced while relatively high prediction precision is achieved.
