Abstract
Due to the complex operation of the compression stress relaxation test equipment used in the national standard, the measurement error is great and the uncertainty and instability of the test result is high, This paper proposes the design of a test equipment with the pressure transducer and digital indicator, which can do real-time monitor on the compression stress of rubber materials in accelerated ageing test. The stress range of the test equipment is 0～980 N, and temperature range 0～200°C. With this equipment, the compression stress in 70°C、80°C、90°C and 100°Cwas tested, and thus the curves of the compression stress at different temperature were obtained.
