WebbCycle counting methods are used to calculate the load spectrum of a load signal, i.e., number of cycles corresponding to each range in a load signal. An example of a load spectrum is depicted in the figure below. Typical cycle counting methods are rainflow counting and Markov counting described in the following chapters.

WebbThe rainflow counting algorithm(also known as the “rainflow counting method”) is used in the analysis of fatigue data in order to reduce a spectrum of varying stresses (strains) into a set of simple stress (strain) reversals.

WebbRainflow counting is used to extract the number of cycles n i and the stress amplitude σ i from the stress history applied to the component. The rainflow counting consists of three steps: Hysteresis filtering: Set a threshold and remove cycle whose contribution to the total damage is insignificant.

There are a number of different algorithms for identifying the rainflow cycles within a sequence. They all find the closed cycles and may be left with half closed residual cycles at the end. All methods start with the process of eliminating non turning points from the sequence.
