Mixed and thermal elastohydrodynamic simulation of a low-loss gear considering the gear system
FrictionThe reduction of load-dependent gear power loss is one of the key aspects in gear design. Therefore, a detailed power loss prediction and the local investigation of its drivers are essential. In this study, the model of Farrenkopf et al.

Friction Characteristics of Microgrooved Bearings under Mixed Lubrication
Tribology Online, 2008 In this paper, the friction characteristics of microgrooved bearings are examined experimentally and theoretically. The microgrooved bearings have an advantage of suppressing the oil film temperature rises under the heavy loaded conditions.

Advanced Materials Interfaces, EarlyView.Macropore‐infused nanocomposite emulsion thermosets (MINETs) offer tunable multifunctionality due to their incorporation of structural resin, functional nanoparticles, and working fluid stabilized by surfactant. Here we show that if ionic liquid working fluids are introduced, structural capacitive (conductive particles) or separator (insulating ...
