Abstract:
The fretting wear is resulted from different or same sample’s surfaces by the small variationand leads to mechanism failures. The main factors consist of the variation of normal load and oscillation frequencies, among which surface topography of different materials are the main factors to the problems of the fretting wear. Therefore, a novel low-frequency reciprocating fretting wear test system is designed upon the principle of Friction coefficient measurement. Four metal and non-metallic samples are measured under various normal load and oscillation frequencies to obtain the instantaneous friction coefficient in the repeat experiments. In fact, the experimental results show that CoF curves of different samples with the increase of the normal load are the similar exponential decay or parabolic shapes, which are consistent with the literatures to verify the rational design and reliable-operation of the system under the conditions of different frequencies.
Key words: fretting wear measuring-head reciprocating platform coefficient of friction oscillation frequency
