Scope
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. Further background information can be found in the SAE publication AE-10 cited in 2.1.1.
Rationale
A standard rainflow file is proposed to facilitate easy exchange of information of the rainflow content of a time history. Various vendor specific formats exist, but this document would allow users to exchange information without the use of commercial file translators.

Issuing Committee
Materials, Processes and Parts Council
The Materials, Processes, and Parts Council (MPPC) promotes, directs, supervises and provides for the development of consensus SAE Technical reports. The council also conducts investigations for activities related to engineered materials, processes and parts used in the surface mobility industry. Participants in the SAE Materials, Processed and Parts Council include OEMs, suppliers, consulting firms, government and other interested parties.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
