摘要
橡胶密封件在飞机舱门结构中广泛应用,主要起到密封、隔音、保温等作用,对飞机的正常飞行以及乘客的生命安全至关重要。该文主要研究了不同截面形状的飞机舱门橡胶密封件在不同条件下的动摩擦性能,介绍了应用于飞机舱门上不同形状的橡胶密封件以及对应的加载装置,并且利用动摩擦性能实验机对不同形状橡胶密封件在不同温度、不同压缩量以及不同表面处理条件下的动摩擦性能进行实验研究,分析环境因素对橡胶密封件动摩擦性能的影响。研究结果对于橡胶密封件动摩擦性能的设计和优化有重要作用。
Rubber seals are widely used in the structure of aircraft doors,which play important roles on sealing,sound insulation and heat preservation.Aircraft door rubber seals are critical to the normal flight of the aircraft and the safety of the passengers.The dynamic friction performances of rubber seals for aircraft doors with different cross-section shapes under different conditions are studied.The rubber seals with different shapes applied to the aircraft door and the corresponding loading device are introduced.The dynamic friction performances of rubber seals with different shapes under different temperatures,different compression displacements and different surface treatment conditions are measured by means of a dynamic friction performance testing machine.The effect of environmental factors on dynamic friction performances of rubber seals are obtained,which is of a great significance for the design and optimization of dynamic friction performance of rubber seals.
