Abstract
The reliability method was applied to analyze the influence of the seal structure parameters on the air-tight performance of aero-port. The Ogden constitutive model was fitted based on compression experimental data of two types of aero-port sealing strip, which was applied to simulate the implicit response of secondary contact force between the door body and door frame by FEM. The seal structure's parameters such as closing-stroke, assembly dimension, and baffle size etc were treated as random variables, the reliability of the two sealing strips types was compared by Monte Carlo method. The mean value sensitivity and variance sensitivity of above parameters were obtained. The results were helpful for the sealing strip selection and seal structure optimum design.
