| Abstract: |
| In response to the reduction in the body armor thickness caused by lightweight armor
vehicles as well as the demand for the high reliability and long life sealing of the vehicles in complex usage
environments such as high salt mist，high and low temperatures，high humidity and heat and strong ultraviolet
radiation，the research on optimization of the high and low temperature resistant and aging resistant sealing
materials，the sealing structure for adaptation to the large deformation components of the thin shell vehicles，
the integral forming process of the large-sized foam sealing rings and the evaluation method of sealing
properties of sealing ring was carried out. The results showed that，after optimizing the sealing technology
system，the vehicle sealing rings could meet the water and air tightness requirements for the large deformation
sealed components of the vehicle body，and their service lives were extended by more than 25%. |
