A high frequency friction rig is used to measure the evolution of hysteresis loops, friction coefficient and tangential contact stiffness over time. This evolution of the contact parameters is linked to significant changes in natural frequencies and damping of the rig. Hysteresis loops are replicated by using a Bouc-Wen modified formulation, which includes wear to simulate the evolution of contact parameters and to model the evolving dynamic behaviour of the rig. A comparison of the measured and predicted dynamic behaviour demonstrates the feasibility of the proposed approach and highlights the need to consider wear to accurately capture the dynamic response of a system with frictional joints over its lifetime.engThis is an open access article under the CC BY license (http://creativecommons.org/licenses/BY/4.0/).The impact of fretting wear on structural dynamics: Experiment and SimulationJournal articleFretting wearNonlinear dynamicsHysteresis loopsFriction coefficientContact stiffnessimpact-fretting-wearhttps://doi.org/10.1016/j.triboint.2019.05.023
