HK40材料剩余寿命预测的推算公式

A Equation to Reckon Residual Life of HK40

本文在统计分析大量HK40性能数据基础上,提出了基于K-D法的HK40剩余寿命外推公式:t_r=exp(ā-10.36logσ+12000/T),其中的值:ā=(1/n)sum from l=1 to n(lnt_n-(42000/T_l)+10.36logσ_l)。公式物理意义明确,并得到良好验证。

Through the analyses of statistic data of HK40,a equation to calculate the residual life of HK40 based on K-D equation has been introduced: t_r= exp(ā-10.36logσ+42000/T) ■The equation tally with the experiment data
