Fretting laboratory tests: analysis of the mechanical response of test rigs

摘要

The Current state of the art of the experimental approach to fretting is discussed. The mechanical response of fretting equipment is analysed to establish the limits of the reliable use of fretting rigs. The effect of stiffness and dynamic response of fretting test rigs are extensively discussed, and a simple one freedom-degree model is proposed to describe, in a first approach, the response of the tangential force measuring systems.
