EXPERIMENTAL STUDY ON DYNAMIC FRICTION PERFORMANCES OF RUBBER SEALS FOR AIRCRAFT DOORS

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.
