Research on wear behavior analysis, modeling and simulation of the integrated control valve

Integrated control valve in the aircraft control system has an important role to play in, spool valve, apartments and will affect a variety of performance indicators in integrated control valve wear, is one of the major failure mechanism. Based on integrated control valve structure and working principle, analysis of spool valve sleeve wear failure sensitive parts and structural parameters affected by wear. Using AMESIM software to model integrated control valve through modeling and simulation of spool valve sleeve due to wear and changes of structural parameters on performance index of integrated control valve. Finally, is worn to physical failure model, based on deviation of product performance thresholds, calculated integration time control valve failure, to propose an integrated control valve service life prediction method.
