要約(英語): In this paper, a numerical analysis of thermo-mechanical viscoelastic material was investigated to predict the compression set of EP-rubber O-rings for substation facilities. Relaxation times for viscous characteristics of this model were calculated by the Arrhenius equation and temperature of rubber. Furthermore, biaxial loading tests by loading test machine and the stress-relaxation tests in the thermal chamber were conducted to evaluate the mechanical and thermal characteristics and effect of temperature on the stress relaxation to confirm the applicability of the simulation code. From the simulated results, the developed code shows enough accuracy to predict the stress reduction of natural rubber parts under the long-term compression.
