Witryna1 wrz 2024 · Stiffness is mainly related to the load distribution caused by the revolution of the cage. Therefore, this study investigates stiffness on the basis of the contact loads. Bearings of type b218 are used, and the external load of bearing F = 2000, 2000, 500, 0, 0 and the rotational speed of bearing n = 5000 rpm are considered. Classical contact mechanics is most notably associated with Heinrich Hertz. In 1882, Hertz solved the contact problem of two elastic bodies with curved surfaces. This still-relevant classical solution provides a foundation for modern problems in contact mechanics. For example, in mechanical engineering and … Zobacz więcej Contact mechanics is the study of the deformation of solids that touch each other at one or more points. A central distinction in contact mechanics is between stresses acting perpendicular to the contacting bodies' … Zobacz więcej The classical theory of contact focused primarily on non-adhesive contact where no tension force is allowed to occur within the contact area, i.e., contacting bodies can be … Zobacz więcej When two solid surfaces are brought into close proximity, they experience attractive van der Waals forces. Bradley's van der Waals model provides a means of calculating the tensile force between two rigid spheres with perfectly smooth surfaces. The … Zobacz więcej • [2]: More about contact stresses and the evolution of bearing stress equations can be found in this publication by NASA Glenn … Zobacz więcej The theory of contact between elastic bodies can be used to find contact areas and indentation depths for simple geometries. Some commonly used solutions are listed below. The theory used to compute these solutions is discussed later in the … Zobacz więcej When two bodies with rough surfaces are pressed against each other, the true contact area formed between the two bodies, $${\displaystyle A}$$, is much smaller than the apparent or nominal contact area $${\displaystyle A_{0}}$$.
