Leakage due to wear is one of the main failure modes of aero-hydraulic spool valve. This paper established a dynamic wear model based on dynamic system modelling theory. Firstly, the wear mechanism between spool and valve sleeve of aero-hydraulic valve is analysed followed by the verification through observation of the wear morphology of the spool surface by SEM. Secondly, the dynamic wear model is established from three aspects of fractional film defect index, Rms of profile, adhesive wear coefficient based on Archard wear model. Lastly, some qualitative analysis on the wear regularity of aero-hydraulic spool valve is conducted based on the dynamic wear model established.
