Prediction of Leakage Based on the Change of the Surface Topography

Abstract:

The aim of this paper is to present a method to predict the leakage of the seal dynamically. The surface of the seal in the sealing area is modeled based on fractal theory. In order to simulate the change of the surface topography during the working process, a meso-scale contact model is set up. The simulation is accomplished with the distinct element software, PFC2D. This will be helpful to predict the lifetime of O-ring in mechanical application.
