Therefore, the research on the gear contact damage evolution mechanism is faced with difficulties such as complex stress states, damage anisotropy and failure modeling. However, traditional fracture mechanics and damage mechanics are limited in predicting the failure load of complex defects and evaluating the structural integrity. Material configurational force theory can describe the effect of defect configurational change on the free energy of materials and be used to predict the damage and failure behavior of materials. In this paper, a wind turbine gear contact damage model is constructed based on this theory. The gear contact interface stress field simulation analysis is carried out for the key bearing area of gear contact, and the gear contact damage evolution process under contact load is simulated. For the problem of gear failure caused by metal oxide inclusion, the damage evolution model based on <em>J</em>_<em>k</em> parameters is established. The damage evolution process of gear containing inclusions under contact loading is simulated numerically, and the influence of depth, shape and location of inclusions on the damage evolution behavior is analyzed. The research results have shown that the configurational force theory damage model can effectively simulate the contact damage phenomenon of gear and explain the pitting and spalling of gear surfaces. It has theoretical significance to predict contact fatigue life of gear accurately.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"202 ","pages":"Article 110391"},"PeriodicalIF":6.1,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142660689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the correlations between built-up angle, surface fractal complexity, and wettability in additively manufactured surfaces using Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS), and Multi Jet Printing (MJT). Surface topography was measured using four optical techniques: focus variation, confocal microscopy, confocal fusion, and interferometry, across multiple scales. The study explored linear, logarithmic, and exponential regression models to identify the best correlations and scale of interactions between the built-up angle, surface complexity, and contact angle. It was found that the built-up angle significantly influences surface fractal complexity, with strong correlations (R² &gt; 0.85) observed particularly at a scale of around 1100 µm². Confocal fusion offered the best reproducibility of measurements, especially at finer scales (&lt; 100 µm²). Surface complexity was also found to correlate strongly with wettability, especially at scales around 1000 µm² and under 10 µm², where exponential regression models performed slightly better, particularly for MJT surfaces. Topographic measurement modes are reproducible with slightly better correlation indices for confocal fusion, between built-up angle and surface complexity. The best correlation of built-up angle, surface complexity and contact angle parameters was obtained for linear regression. The results suggest that surface wettability can be controlled by adjusting the built-up angle, with FDM and SLS surfaces transitioning from hydrophobic to hydrophilic as the angle increases beyond 70 degree, while MJT surfaces remained hydrophobic even at higher angles. The built-up angle parameter allows modeling wettability in the range of 80–120°.
