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.

The wheel-rail contact friction influence on high speed vehicle model stability [PDF]

open access: yesTransport Problems, 2015
Right estimating of the coefficient of friction between the wheel and rail is essential in modelling rail vehicle dynamics. Constant value of coefficient of friction is the typical assumption in theoretical studies.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
