A new model was developed for the simulation\nof the friction coefficient in lubricated sliding line contacts.\nA half-space-based contact algorithm was linked with a\nnumerical elasto-hydrodynamic lubrication solver using the\nload-sharing concept. The model was compared with an\nexisting asperity-based friction model for a set of theoretical\nsimulations. Depending on the load and surface\nroughness, the difference in friction varied up to 32 %. The\nnumerical lubrication model makes it possible to also\ncalculate lightly loaded contacts and can easily be extended\nto solve transient problems. Experimental validation was\nperformed by measuring the friction coefficient as a function\nof sliding velocity for the stationary case.
