00925njm 22002777a 4500 dc Zabala, Alaitz author Abbasi, Farshad author Llavori, Inigo author 2020 In this work, the role of the contact stiffness in the measurement of principal variables in fretting wear tests is assessed. Several fretting wear tribometers found in the literature, including one developed by the authors, are analysed and modelled using numerical methods. The results show the importance of the tribosystem stiffness and tangential contact stiffness in the displacement sensor calibration and in the correct numerical modelling of fretting wear tests, especially for flat-to-flat contact configuration. The study highlights that, in most cases, direct comparisons between fretting results with severe wear obtained with different tribometers cannot be performed if the contact stiffness is not properly considered during the development of the experiments. 1424-8220 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=159473 https://hdl.handle.net/20.500.11984/1806 fretting wear tangential contact stiffness numerical modelling On the Role of Contact and System Stiffness in the Measurement of Principal Variables in Fretting Wear Testing
