Abstract

Aiming at the prediction problem of metal contact sealing performance,the orthogonal experimental method was used to fit the functional relationship between surface topographical parameters, applied load and contact area ratio based on the numerical representation of rough surface and finite element contact analysis.Combined with the grid model of percolation theory, the variation rule of seal leakage probability with contact area ratio was simulated by using automatic path-finding algorithm. Therefore, a quantitative analysis method for predicting the relationship between rough surface topography with applied load and sealing performance was established, which can provide guidance for designing metal contact seal.
