Computer graphics visualization technology is introduced to rubbing fault recognition for the research on aircraft engine rubbing fault recognition. First of all,visual graphic models of aero- engine key components such as rotor blade and casing are established; then according to the displacement of the vibration of the rotor and the casing,rubbing positions are detected; finally rubbing sparks when rubbing fault appears are simulated so that the rubbing fault can be showed intuitively. Finite element simulation experiments of rubbing fault are used to verified the new method,and the results show that this method can effectively identify the rubbing fault and intuitively show the rubbing effect.
