摘要
提出了可靠性分析的三参数法,它不仅考虑了随机变量的均值和方差,还计入分布偏度的影响。由于三参数法较多地保留了随机变量的分布特征,从而提高了可靠性分析的精度。
A new three-moment method is presented. The proposed method considers not only the means and variances of random variables, but also the influences of skewness of probabilistic distribution. Because more characteristics of random variables to be concerned with reliability analysis are maintained, the precision of reliability analysis can be increased. This is highly important for aeronautical products with high reliability requirement.
