Steady-state Friction Characteristics of Contact Mechanical Seal
Shiyou jixie, 2023 The contact mechanical seal is mainly in a mixed lubrication state during operation, and its end clearance and surface roughness are in the same order of magnitude.In order to explore the friction and wear characteristics of contact mechanical seal in ...

Application of Load-Sharing Concept to Mechanical Seals
Lubricants, 2023 Mechanical seals are mechanisms that are used to prevent fluid leakage. Since the seal surfaces are in contact with one another, hydrodynamic and contact forces are functions of surface roughness. Additionally, since the lubrication regime under specific

Advanced Healthcare Materials, EarlyView.This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Mixed and thermal elastohydrodynamic simulation of a low-loss gear considering the gear system
FrictionThe reduction of load-dependent gear power loss is one of the key aspects in gear design. Therefore, a detailed power loss prediction and the local investigation of its drivers are essential. In this study, the model of Farrenkopf et al.
