摘要
针对某自然贮存场近几年的自然环境因素数据,应用小波分析理论对温度数据的周期分量和随机分量进行了分离。在数据分离的基础上,根据阿仑尼斯方程对年温度数据的周期分量,进行了等效平均,获得以热天、冷天划分的年恒定温度剖面。根据Manson-coffin模型对温度数据的随机分量进行了等效循环处理,最后综合得到贮存场的试验室模拟试验应力剖面。文中所有统计归纳均应用了MIL-STD-810中所建议的容差数据处理归纳方法。
The theory of wavelet was used to separate the periodic component and the stochastic component of temperature data from recent years′natural environmental data of a certain natural storage station.Equivalent mean was processed on the periodic component of annual temperature data using Arrhenius equation.The temperature profile was formulated by drawing isothermal curve of hot days and cold days in a year.Equivalent circulation treatment was processed on the stochastic component of annual temperature data using Manson-coffin equation.The stress profile of the natural storage station for laboratory simulation test was formulated from the integration of above.The induction data was carried out in accordance with MIL-STD-810.
