    Hi,

    does any know, how I can calculate a load spectrum out of a Rainflowmatrix?

    I have classified a load-time-signal with the rainflow classification method into a rainflow-matrix.
    Now, I would like to derive the mean-stresses, the associated stress-amplitudes and the absolute frequencies of the stress-amplitudes to use it for further fatigue-strenth-calculation.

    Answers in German are welcome also.

    Best regards

    You can use thr [b]Rainflow Count Analyis Object[/b] to derive univariate collectives from an existing Rainflow matrix. These one-dimensional results can be plotted and compared more easily.

    See the FlexPro help for more details.
