The fatigue damage threshold with a reliability and a confidence is suggested in this paper.
还给出了带有可靠度和置信度的疲劳损伤阀值。
Therefore, the distribution configuration of the fatigue damage threshold is the same as the distribution configuration of lineal cumulative damage.
因此，新定义的疲劳损伤阀值与线性累积损伤之间在分布形态上是一致的。
The fatigue damage threshold observes the normal distribution under the condition of the logarithmic fatigue life observing the normal distribution.
疲劳寿命在一定显著水平下服从对数正态分布，由此可以证明疲劳损伤阀值服从正态分布。
The threshold value of damage and maximum strain are adopted as failure criterion to reflect fatigue failure and ductile failure respectively.
针对材料不同的失效模式，分别采用损伤变量门槛值和最大应变作为失效判据。
Finally the threshold value of load amplitude that influences fatigue life of wheelset is calculated based on the principle of equivalent damage and damage distribution agreement.
依据损伤等效和损伤分布一致原则，计算得出了影响轮对疲劳寿命的载荷幅值门槛值。
