Besides counting up loading cycles,it still needs to record loading sequence effects by dividing loading history into phases and putting them in cases as loading history is treated.
当处理载荷历程时，提出了除统计出载荷循环外还需要用分段装箱方法记录载荷顺序效应。
The present paper builds two dimensional loading distribution, and constructs three kinds of fatigue spectra according to the damage laws of the loading sequential effects.
首先建立了二维载荷谱分布,然后依据载荷顺序效应损伤机制编制了3种疲劳谱。
By analysis of the loading sequential effects and arranging sequential effects of the spectra from two dimensional loading distribution, it is found that the loading sequential effects are only influenced by the total mean value of loads and it is possible to influence life prediction greatly as the total mean value increases.
通过二维分布谱的载荷顺序效应与排列顺序效应分析得出,谱载荷顺序效应仅与载荷总均值有关,并随其增大有可能对寿命预测影响较大。
