标准雨量文件格式

[中文适用范围]： 该 SAE 标准提供了 rainflow 文件格式的定义。这种类型的简单文本文件将包含有关时间历史的雨流循环内容的所有相关信息。包含的信息包括注释@信号范围@信号平均值@周期数@信号最大值@信号最小值。雨流循环计数已成为在复杂的变幅负载时间历史中识别材料疲劳相关循环的最被接受的程序。周期计数方法考虑了材料塑性和先前变形的材料记忆的影响，并且耐久性分析师使用由此产生的压缩历史信息来估计给定服务或测试历史的影响。雨流计数方法输出文件的标准化@是本标准规定的格式@对于测试和设计组@或不同计算软件包@之间可靠的信息传输非常重要，因此构成了组件和车辆评估的关键步骤。更多背景信息可参见 2.1.1 中引用的 SAE 出版物 AE-10。 [外文原描述]： This SAE Standard provides a definition of a rainflow file format. This type of simple text file would contain all relevant information about the rainflow cycle content of a time history. Included information are Comments, Signal Range, Signal Mean, Number of Cycles, Signal Maximum, Signal Minimum.Rainflow cycle counting has become the most accepted procedure for identifying material fatigue relevant cycles in complex variable amplitude load time histories. The cycle counting methods account for the effects of material plasticity and material memory of prior deformation, and the resulting compressed history information is used by durability analysts to estimate the effects of a given service or test history. Standardization of the rainflow counting methods output files, which is the format addressed by the present standard, is important for reliable information transfer between test and design groups, or different calculation software packages, and thus forms a critical step in the evaluation of components and vehicles.
