Abstract

An accelerated ageing test equipment with the pressure transducer and digital indicator is designed in the light of the features that the rubber seal used in aviation industry always stand compression stress. This equipment can do real-time monitor on the compression stress of rubber materials in accelerated ageing test. The stress measurement range is 0~980 N, and the temperature fluctuation range is 0~200°C. With this equipment, the compression stress relaxation and stress permanent set can be tested and the relationship between them in 100°C can be found.
