摘　　要：航空作动器主密封是典型的往复密封,广泛应用在飞机机翼、舱门等众多部位。它的失效会直接影响飞行安全,甚至会造成重大的人身事故,因此对其密封结构参数进行分析具有重要意义。本文以往复密封作为研究对象,建立往复密封混合润滑模型,以摩擦力、反向泵回率及接触区接触压力最大值作为评价密封性能好坏的指标,分别改变油侧倾角、空气侧倾角,改变密封唇表面粗糙度,对密封结构进行参数化分析。The primary seal of aircraft actuators belongs to typical reciprocating seals, which is adopt as a component of the wings, doors, and many other parts of an aircraft, Its failure will directly affect flight safety, and even cause major accidents, therefore it is a great significance to analyze its sealing structure parameters. In this paper, Reciprocating seals were taken as the research object, it establish a reciprocating seal mixed lubrication model, and used the friction ,reverse pump rate and maximum pressure in contact area as evaluation of sealing performance, made parametric analysis of seal structure by changing oil roll Angle, air roll Angle ,and the surface roughness of the sealing lip.
