Fatigue Testing with Flexpro: Counting
Would you like to use FlexPro to analyze load-time functions? Counting provides you with an indispensable analysis tool.
Counting is based on a search for specific events in the load-time function, e.g. a certain load level being exceeded or a load alternation of a certain amplitude. For this purpose, the range of values of the load-time function is divided into discrete intervals, or classes. Each event found is assigned to a class and counted in this class.
Performance Features
Matrices
Markov matrix and Rainflow matrix in range-mean format as well as symmetrical and asymmetrical from/to format. The residual of the rainflow count can optionally be included in the result.
Range Filter
Suppresses small load changes.
Class Divisions
Automatic, via start and width of class, begin and end, symmetrical or via external data set.
Derived Collectives
Peaks and troughs, positive and negative ranges and range pairs, positive and negative level crossings.
Frequencies
Absolute, relative, percentage and cumulative.
Counting Procedures According to DIN 45667
Sampling, maximum value and time-at-level.
Compound Counting Procedures According to DIN 45667
Sampling, maximum value and time-at-level from two input data sets with separate class division for each data set.
