Simplified prediction of stability limit for oil film bearing rotor systems
Nihon Kikai Gakkai ronbunshu, 2020 Oil film bearings are often used in large rotating machinery because they have large load capacity and damping coefficients. They, however, generate fluid forces and cause unstable vibrations such as oil whirl and oil whip at high rotational speed ...

Elastic Deformation Effects on Self-Lubricating Journal Bearings Using Pseudo-Plastic Lubricants
Tribology Online, 2021 In this study, we have analyzed the effect of elastic deformations on the static characteristics of finite self-lubricating journal bearings. This analysis takes into account the rheological lubricant behavior which obeys to Rabinowitsch law.
