RISA Simplified Thermal Analysis of Elastohydrodynamic Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Under elastohydrodynamic (EHL) conditions, the temperature in the contact zone determines the load resistance of the lubricant film. Therefore, an efficient assessment of the scuffing risks requires accurate contact ...
A Fast Thermoelastic Model Based on the Half-Space Theory Applied to Elastohydrodynamic Lubrication of Line Contacts Involving Free Boundaries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study allows contact models based on semi-analytical methods including the impacts of thermoelastic deformations in contacts of finite dimension bodies. The proposed method controls heat flows crossing free boundaries. ...
Numerical Investigation of Deep Surface Texture Performance Using a Finite Element Solution of the 2D Navier–Stokes Equations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study presents a numerical investigation of the hydrodynamic performance of textured surfaces under lubrication, emphasizing the influence of texture geometry and manufacturing defects. Rectangular and ...
An Efficient Semi-Analytical Method for Modeling Contacts in Multilayer Helical Strand Cables Under Microslip Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Multilayer cables are extensively used owing to their high strength, flexibility, and durability. Under external forces, cyclic loadings induce slip and microslip at strand contact points, leading to fretting, ...
