摘要：

Nitrile Butadiene Rubber (NBR) is a kind of common sealing materials for the electric hydraulic servo mechanism, there exists the aging failure problem in its storage environment, which is the key factor determining the storage life of the electric hydraulic servo mechanism. Through the analysis of aging failure mechanism of the NBR o-ring, the degradation path that varies with the changes of aging time based on compression set was established. And the Arrhenius equation, which is the acceleration equation of the aging reaction velocity varies with the changes of temperature, was established as well. In order to obtain the related parameters of the model, the accelerated aging test was conducted and its data were processed by applying the approximation standards and least square method. Also through the test the prediction of storage life of NBR o-ring under special storage conditions was made, and its predicted results were basically identical with the actual storage life.
