In this study, we propose a finite element model to investigate the fatigue behavior of a double-helical planetary gearbox based on the critical plane methods with a search algorithm to improve calculation efficiency. The finite element mesh is generated along the direction of the contact line to accurately capture contact stress. The time-varying coefficient of friction between contact surfaces and the residual stress in the hardened layer are considered in the developed model. The effectiveness of the model is demonstrated by comparing the predicted fatigue life with measured data from experiments for a spur gear planetary train. It is concluded that the ability of the planet gear to resist contact fatigue dominates the service duration with fatigue cracks initiating nearly parallel to the surface. The surface hardness gradient is recommended to ensure reliable operation throughout its designed life.</p>\u0000 </div>","PeriodicalId":12298,"journal":{"name":"Fatigue & Fracture of Engineering Materials & Structures","volume":"48 4","pages":"1429-1446"},"PeriodicalIF":3.1,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, a cyclic cohesive zone model considering the elastic–viscoplastic mechanical response of the bulk material is established, which further verified that more plasticity deformation is introduced near the crack tip at reduced loading frequency, thus imposing more damage accumulation to the crack tip.

The low-cycle fatigue (LCF), high-cycle fatigue (HCF), and very high cycle fatigue (VHCF) life ranges have been considered in the analyses. Design curves should take into account the randomness associated with the material parameter estimation and model it in a probabilistic framework. The analyses carried out in the paper have shown that methodologies based on shifting the median curve or the best-fitting curve by a fixed safety factor or a safety factor dependent on the reliability and confidence targets are among the most used. On the other hand, in several research works, more complex statistical models and methodologies, for example, based on the maximum likelihood principle or the bootstrap approach, have been proposed but are less widespread because they require a more complex implementation.
