采用可靠性思想分析飞机舱门密封结构参数对密封性能的影响。对两种型号的舱门密封带进行整体规格的压缩实验,拟合成Ogden模型代入有限元计算获得门体与门框的二次接触力的隐式响应关系。将关门行程、装配尺寸、挡件尺寸等视为随机变量,采用MonteCarlo法对两种密封带的气密可靠性进行比较,得到了密封结构参数的均值灵敏度和方差灵敏度,对舱门密封带选型与结构的优化设计提供参考。 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.
