Mechanical face seals are widely used in air vehicles. The existence of random vibration load is a very important environmental factor. A dynamic model for mechanical face seals is proposed, The mechanical face seal in the axial direction is described as a mass-spring-damping system. A method to relate random vibration and sinusoidal vibration is proposed based on the equivalent damage theory. The effects of the random vibration power spectral density (PSD) value, axial stiffness and axial damping on wear are analyzed. The results elucidated that the increase of input power spectral density (PSD), the increase of axial stiffness and axial damping will lead to the increase of wear.
