Abstract

The steady-state operation of a polymer journal bearing is investigated by means of an innovative numerical methodology, based on the definition of a viscoelastic Green’s function intrinsically accounting for the circular hallmark of the contact domain. Crucially, results show, in terms of pressure, film thickness, and friction, the occurrence of a peculiar viscoelastohydrodynamic (VEHL) regime. This has critical consequences in applications, where the bearing capacity of the system may be affected. Ultimately, by focusing on different contact configurations, we show that the VEHL regime in polymer journal bearings is governed by three independent parameters, namely the Hersey number and the dimensionless velocities of the two interacting bodies.

期刊介绍: The International Journal of Solids and Structures has as its objective the publication and dissemination of original research in Mechanics of Solids and Structures as a field of Applied Science and Engineering. It fosters thus the exchange of ideas among workers in different parts of the world and also among workers who emphasize different aspects of the foundations and applications of the field. Standing as it does at the cross-roads of Materials Science, Life Sciences, Mathematics, Physics and Engineering Design, the Mechanics of Solids and Structures is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from the more classical problems of structural analysis to mechanics of solids continually interacting with other media and including fracture, flow, wave propagation, heat transfer, thermal effects in solids, optimum design methods, model analysis, structural topology and numerical techniques. Interest extends to both inorganic and organic solids and structures.
