The fretting wear behavior of Ti-6Al-4V dovetail assemblies under resonant vibration was investigated using fan blades manufactured with real geometry and a newly developed vibration test platform. The effects of clamping level, excitation load, and cycle number on resonance response and surface wear were analyzed. An energy dissipation based model was proposed to predict wear evolution.
