    Abstract
  • Experimental research on load decay of two kinds of O-ring made of different silicone rubber under different temperature has been conducted. The results show that the load decay characteristic of the O-ring is related to the material of the O-ring, and temperature can change load decay characteristic, the speed of load decay increases with the rise of O-ring temperature. By the study to the theory of load decay and analysis to the results of experiments, a theoretical model has been conducted to describe the load decay characteristic of the O-ring,it matches the results of the experiments very well.
