Toward that end, it is necessary to investigate the lubrication conditions of engine sliding surfaces and instantaneous heat flux in the combustion chamber in order to obtain experimental data for validating computer-aided engineering (CAE) calculations. The authors used thin-film sensors to measure the distribution of the oil film pressure on the sliding surfaces of engine parts including pistons, bearings and gear tooth surfaces. This paper describes the structure and configuration of the thin-film sensors and the measurement system used for direct observation, especially of piston pins, and presents the measured results.","PeriodicalId":23314,"journal":{"name":"Tribology Online","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136227797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One wall is smooth and sliding on the other fixed dimpled wall with constant velocity. Effect of star shaped dimple and oriented star shaped dimple has been compared with circular shaped dimple for hydrodynamic pressure generation and tribological behaviour. Effect of dimple depth, dimple area density and sliding speed on tribological behaviour were also analyzed. The results demonstrate that an unconventional star-shaped and orientated star-shaped dimple produces a larger net hydrodynamic pressure in the fluid domain and provides better stability between the sliding surfaces than a circular-shaped dimple. It is shown that geometric parameters like dimple depth and dimple area density and operation parameter like sliding speed affects the hydrodynamic average pressure and tribological behaviour of sliding surfaces significantly. The experimental findings validate the analytical and CFD findings.","PeriodicalId":23314,"journal":{"name":"Tribology Online","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136227794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The graphite nanoparticle is divided into the two parts along the normal direction: the part contacts to the iron plate is controlled temperature and the lower other is held in the frozen situation. We detect the friction dependent on the frozen height, the angle between the sliding direction and the graphene surfaces by rotating the graphite nanoparticle around the normal direction, the external load and the sliding speed. The friction is low in all the investigated cases, the friction coefficients ~ 0.004 to 0.066. The sliding speed slightly results in the friction, while the other factors significantly influence it.","PeriodicalId":23314,"journal":{"name":"Tribology Online","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136227634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key feature is the ability to absorb sweat during physical activity, which can, however, cause discomfort due to stickiness. This study focuses specifically on the stickiness caused by sweat between sportswear and the skin by objectively evaluating stickiness using specific physical parameters and correlating them with sensory evaluation values. Moreover, there is little research on the adhesion force between sportswear and human skin. Therefore, this study aims to achieve the following objectives: (1) investigate the relationship between the adhesion force between human skin and fabrics and the sensation of stickiness; (2) examine the relationship between the adhesion force between artificial skin and fabric and that between human skin and fabric; and (3) clarify the impact of fabric wettability and geometry on the adhesion force under wet conditions. Experiments reveal that the sensory evaluation value and adhesion force against human skin corresponded. Additionally, a positive correlation was found between the adhesion force against human skin and an artificial skin sheet. These experimental results suggest that fabrics with a lower adhesion force can be achieved by decreasing the load area ratio at 30% Φ0.3 and increasing the contact angle and meniscus height.","PeriodicalId":23314,"journal":{"name":"Tribology Online","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135809047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
