Numerical model to predict wear of dynamically loaded plain bearings

Wear resistance of dynamic system components is a major challenge in aeronautics. According the usage aircraft, off-centred loads can appear on shafts when rotating bodies are unbalanced. In literature, most wear studies applied to plain bearing consider static centred contact area. This article presents study submitted order look for better mastering service life their severe aeronautic conditions. Boussinesq's equations were used compute pressure distribution and Archard's law was calculate wear. The coefficients running-in stable stages defined experimentally. evolution over time maximum depth size zone validated with experimental results. perspective this work feed digital twins systems predict according aircraft usage.
