In the paper findings are discussed on the issue of dynamic characteristics of a tribometer as a factor influencing the result of the tribological experiment. An advanced approach to tribo-testing is attempted with integrated dynamic analysis of the tribometer and the sliding pair. The fundamental idea is explored of the tribometer being regarded as any machine in which friction is inflicted with all the resulting consequences such as e.g. wear, vibration, fatigue etc. The research described is concentrated around friction induced vibration and it’s potential consequences to the results obtained in a tribological experiment. General methodology used for the task described is presented.
