Research on Aging Equivalent Temperature under Variable Temperature Environment

Based on the Arrhenius equation, the aging equivalent temperature model in a variable temperature environmentis derived, and the aging equivalent temperature under the actual monitored ambient temperature is calculated. Accordingto the statistical models and data of environmental temperature in different sea areas, aging equivalent temperatures of dif?ferent sea areas are obtained, which provides a reference for aging calculation and accelerated experimental scheme designunder variable temperature environments. It is shown by the results that the ambient temperature changed alternately un?der the effect of season and day-night; the aging equivalent temperature is higher than the average temperature and is posi?tively correlated with the activation energy; both the aging equivalent temperature and the long-term aging accumulationof high temperature sea area are increased.
