Analysis of Static Characteristic of Hydrodynamic Bearing with Different Surface Roughnesses

open access: yesJixie chuandong, 2020
When the working surface roughness of hydrodynamic sliding bearing reaches the same magnitude (micron) as the oil film thickness, the influence of surface roughness on the characteristic parameters of bearing cannot be ignored.

Effects of the oceans on polar motion: Continued investigations [PDF]

open access: yes
Data on the pole tide, the oceanic response to the Chandler wobble were presented. Observed North Sea pole tide enhancement (i.e., larger amplitudes than a static tide would possess) resulted from bottom friction, with the drag coefficient, in ...

Friction Coefficient of a Ladyfinger Banana Peel

open access: yesInternational Scholastic Journal of Science, 2020
The coefficient of static friction of a lady finger banana peel was investigated for varying values of vertical compression force. The peel was placed on a tile surface, with a person placing her Converse sneaker on the peel and pushing down with force ...

Effect of Indentation Depth on Friction Coefficient in Adhesive Contacts: Experiment and Simulation

open access: yesBiomimetics
The quasi-static regime of friction between a rigid steel indenter and a soft elastomer with high adhesion is studied experimentally. An analysis of the formally calculated dependencies of a friction coefficient on an external load (normal force) shows ...
