就是在ASTM E1049-85规范中记载的常规的雨流计数的步骤,该算法在没有数据重新安排的情况下起作用,因此无需提前知道绝对最大值,可以进行实时的雨流计数。从原始谱出发采用三点雨流计数的方法,用连续的三个点判断是否形成迟滞环即可以记为1个cycle的范围。连续的三点形成两条线段,根据线段的长度判断是否形成迟滞环...
随着研究的深入,人们发现采用时间序列计算载荷谱太麻烦了,处理的工作量太大,我们不需要将每个时刻点的载荷都做运算,疲劳计算只需要提供**幅值**、**均值**和**循环次数**,鉴于此发展出了很多不同的计数方法,雨流法是最常见的处理方式,在ASTM E1049-85规范中记载了常见的4种计数方法。
