摘要
针对载荷累积频次分布 ,提出了一种确定某个应力水平下累积频次的方法 ,与其它已有方法进行误差对比分析 ,可看出本方法能大大提高精度。在疲劳试验中 ,可应用于形成载荷程序块 。
In view of load cumulative frequency distribution, a new method is put forward which can be used to obtain cumulative frequency on a certain stress level. Compared with other methods about error analysis, it shows that the method can greatly improve the accuracy. In fatigue tests, it can be applied to draw up a loads program block, and it can predict the fatigue life more accurately.
