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.
