Abstract

A method for determining load cycles uses a first buffer containing a first value of a physical variable in a first position and a second value thereof in a second position. A measured third value is stored in a third position. A Rainflow filter is applied, it is checked whether a point of inflection results between the first value and the third value. If the second value forms a point of inflection, then the first position is overwritten with the second value, the second position is overwritten with the third value, the second value is discretized and stored as the last entry in a second buffer. If a second-from-last entry and third-from-last entry form a load cycle, then these values are registered in a Rainfall matrix and removed from the second buffer, and the second buffer is again checked for a load cycle.
