Influence of Surface Microstructure Parameters on Wear of Bearing Steel Ball Unfolding Wheel
Journal of Harbin University of Science and Technology, 2021 In order to study the dry friction wear relationship between the bearing steel ball unfolding wheel with the surface microstructure parameters (area, shape and depth), the orthogonal test method was used to test the microstructure with different ...

Wear transitions in a wear coefficient model [PDF]
Wear, 2009 The frictional-work wear model has been used popularly for the prediction of wear phenomena such as rail corrugation. The accuracy of such models depends on the value chosen for the empirical wear coefficient in this wear model. Experimental results have widely shown that this wear coefficient is strongly dependent upon the type of wear process ...

Friction, 2023 The wear profile analysis, obtained by different tribometers, is essential to characterise the wear mechanisms. However, most of the available methods did not take the stress distribution over the wear profile in consideration, which causes inaccurate ...

Wear Assessment in High Cycle Rolling Contact Fatigue Using Semi-Analytical Approach [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013 Presented paper deals with ratcheting prediction in the field of contact fatigue for the case of line contact. For the stated purposes, the wear model proposed by A. Mazzu [1] is used, which stands out for its simplicity and time efficiency. The model is

Mechanical modelling of tooth wear [PDF]
Journal of The Royal Society Interface, 2016 Different diets wear teeth in different ways and generate distinguishable wear and microwear patterns that have long been the basis of palaeodiet reconstructions. Little experimental research has been performed to study them together. Here, we show that an artificial mechanical masticator, a chewing machine, occluding real horse teeth in ...

Wear and Leakage Behaviors of Brush Seal Considering Eccentricity and Radial Deformation
Energies, 2023 Brush seals can improve engine performance by reducing leakage. Wear models of brush seals provide methods to predict wear and leakage. However, rotor eccentricity, radial deformation, and hysteresis effect of bristles are not considered systematically ...
