前面叙述了载荷的各种幅值域统计特徵参数,在有限寿命设计和试验中用得最多的是载荷的幅值分布,即载荷幅值的大小和其出现的频次或频率(近似概率)或概率密度或概率分布。大部分载荷是一个随机的连续
In the previous sections, the statistical characteristics of the various amplitude domains of the load are described. The most commonly used load distribution in the finite life design and test is the magnitude of the load and its frequency or frequency (approximate probability) or Probability density or probability distribution. Most loads are a random continuum
