Summary:Due to legislative requirements companies are enforced to take on demanding engineering challenges in order to fulfil targets regarding CO2-emissions and pollutions. Especially the automotive industry has come up with a range of technologies throughout the past decade to reduce the amount of exhaust gases. Tribology has played an important role and will be significant in the future when it comes to creating environment-friendly machines. Especially machine elements, such as gears, camshaft or roller-bearings, which are referred to as non-conformal machine elements from here on, are heavily loaded and have to operate under severe conditions. Often this results in the energetically unfavourable mixed friction state, which means that the total external load is shared by the oil and micro contacts. The current work is focused on methods for modelling these micro contacts in order to take them into account in state of the art EHD (elastohydrodynamic) models. This enables an in depth analysis of highly loaded machine elements in order to optimize machine elements sustainably.
