摘要: 提出了用重要性抽样的ＭｏｎｔｅＣａｒｌｏ模拟法计算管节点的疲劳失效概率，并与直接抽样的ＭｏｎｔｅＣａｒｌｏ法进行了比较，结果表明：用重要性抽样法计算可大幅度地提高计算效率Abstract: The paper calculates the fatigue failure probability by using Monte carlo simulation method of important sampling, and compares with the direct Monte carlo method. The results show:the important sampling method can greatly imporve calculation's efficiency.
