摘要
用概率统计方法研究了构件在成组法疲劳试验中的安全寿命和寿命分散系数 ,用单侧容限系数法计算了 1Cr18Ni9Ti材料及焊接接头的寿命分散系数 ,并对计算结果进行了讨论。
The safe life and the life diffuse factor in grouping component fatigue test are studied with the probability statistic methodology. The life diffuse factor of 1Cr18Ni9Ti and its welding joins is calculated with one-side tolerance factor method and the results are discussed.
