| 摘 要： | 标准载荷累积频次谱的引入给构件疲劳寿命预测方法的研究和应用带来了方便。但是,对于这种累积频次谱的外推却没有相应的简便方法。为解决这一问题,本文提出了仅以计算分析为基础的标准载荷累积频次谱的外推方法。文中所导公式适用于各种起讫范围的外推计算。通过与以往的方法相比较,所得外推结果令人满意。

| Abstract: | The introduction of the standard load collection curves is of benefit to the
research and application of the predicting methods of the construction fatigue
life. But there have never been easy corresponding reseach methods for the extra-
polation methods of this load collection curves. For resolving this question, ex-
trapolated methods of standard load collection curves only based on accounting
analytics are put forward in this paper. The formulas in this paper are suitable
for every extrapolating account. By comparing it with the previous methods,
the extrapolating results are satisfactory. |
