2. 1. Friction in highly pressurized lubricants and its relation to thermo-physical properties

   Author : Bert-Olof Åhrström; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Abstract : The objective of this work was to increase the understanding of which lubricant properties control transient friction, and during what environmental conditions friction is minimized. The experiments have been conducted during conditions relevant to an elastohydrodynamic contact, with pressures extending up to 2. READ MORE

4. 2. Influence of transient loading on lubricant density and frictional properties

   Author : Bert-Olof Åhrström; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Abstract : This licentiate thesis deals with the influence of transient loading, at high pressures, on the pressure-dilatation relation and frictional properties of lubricants. A Split-Hopkinson pressure bar and a Ball and Bar apparatus have been used for the experiments. READ MORE
