Abstract
Abstract The sealing structures, found in various equipment used in daily life, industry, and the military, play roles in preventing leaks, contamination, and toxic gases. This study focuses on the sealing interface of hyperelastic rough surface, employing an iterative algorithm to calculate the leakage process under fluid action and determine the critical leakage pressure. By substituting the fluid load on the sealing interface before leakage with a uniformly distributed pressure, this algorithm accurately identifies the boundaries of fluid and sealing contact regions through continuous iteration. Consequently, it solves the sealing interface state under a certain pressure and incrementally increases the hydrostatic pressure to obtain the critical leakage pressure. This research visualizes the sealing leakage process and determines the critical leakage pressure of the sealing interface, offering practical value for engineering applications and providing guidance for the design and manufacturing methods of sealing components.
