The equations of motion a rotor system mounted on journal bearings with non-linear characteristic are solved by high-precision analytical methods. A new technique has been developed for solving nonlinear differential systems bearings, taking into account nonlinearity reaction forces the lubricating layer. Algebraic were obtained that allow us to determine amplitudes oscillations and supports, c...
In order to compute the thermal deformation of the hydrostatic thrust bearing in the heavy type CNC equipments, a numerical research concerning temperature field of multi-pad hydrostatic thrust bearing having sector cavity, rectangular cavity, Ishaped cavity and ellipse cavity is described. Three-dimensional temperature field of gap fluid between the rotation worktable and the base has been sim...
Articular cartilage can resist a significant amount of mechanical stress and provide a lubricating surface for the gliding joints and a load-bearing matrix attached to the underlying bone [1]. However, due to its avascular nature and low metabolism, it has a very limited self-repair capability upon suffering a trauma [2]. The disease control and prevention center reported that nearly 27 million...
Antifriction self-lubricating glass composite coatings of the Sic-Ni-Cu-Al-Si-C type additionally contain an aluminoborosilicate phase and structurally free MgC2, which forms α-graphite during thermolysis, synergistic effect causes modification friction surface due to formation antifriction layer. The influence structural components coating on their contribution properties is considered. It was...
Nitrile-butadiene rubber (NBR) and another polymer with an excellent self-lubricating property are blended to develop a new kind of polymer used for water-lubricated stern bearings. The tribological performance of the new Polymer Blend of NBR (PBN), with the comparison of a rubber common used for most stern bearings, was studied using a stern bearing test rig of SSB-100. The results showed that...
