摘要
基于阿伦尼乌斯(Arrhenius)公式,推导得到了变温环境下的老化等效温度模型,并根据实际监测的环境温度数据,计算了实测环境温度下的老化等效温度。在此基础上,根据不同海域环境温度统计模型及数据,得到不同海域老化等效温度,从而为变温条件下的老化计算和加速试验方案设计提供了参考。研究表明,环境温度受季节和昼夜变化影响,呈现交变的特点;老化等效温度大于平均温度,且与活化能的变化正相关;在高温海区贮存,其老化等效温度将增加,长期老化累积也将增加。
Based on the Arrhenius equation,the aging equivalent temperature model in a variable temperature environment is derived,and the aging equivalent temperature under the actual monitored ambient temperature is calculated.According to the statistical models and data of environmental temperature in different sea areas,aging equivalent temperatures of different sea areas are obtained,which provides a reference for aging calculation and accelerated experimental scheme design under variable temperature environments.It is shown by the results that the ambient temperature changed alternately under the effect of season and day-night;the aging equivalent temperature is higher than the average temperature and is positively correlated with the activation energy;both the aging equivalent temperature and the long-term aging accumulation of high temperature sea area are increased.
