Abstract

Based on the research on elastomer contact mechanics theory and percolation theory, this paper analyzes the sealing performance of metal rubber from the micro perspective of sealing coupling surface topography. By constructing the function of contacting rough surface height, the leakage model of metal rubber material seal is achieved. Comparing the leakage situation under different amplification factors, the critical amplification factor is achieved and the empirical equation to predict the leakage rate of metal rubber is given. The equation calculated the leakage rate under different working conditions and the calculated value highly fits the theoretical value, thus obtain the changing rule of the leakage according to the change of temperatures and pressures. Besides, it also provides certain reference for predicting the sealing performance of metal rubber under certain temperature and pressure.
