Rainflow counting is the basis for several further counting methods like Level-Crossing and Range-Count, Peak Valley etc. and it's also the basis for damage calculation based on the Miner algorithm.
To consider multi axial loads, like Fx, Fy, Fz, Mx, My, Mz acting at a wheel also multidimensional Rainflow counting is supported.
Rainflow counting results can be added or multiplied to get to know the loads of the whole life time of a structure.
To analyze rotating loads beside Rainflow counting also time at level counting is necessary to be able to determine life time.
Time at Level counting methods are supported from one dimensional up to three dimensional load situations (i.e. gear, speed and torque).
Further counting methods for special use.
All counting results can be visualized. Rainflow results also may be edited in an graphical way.
Counting results may be compared with help of 2 dimensional plots.
The miner algorithm is the commonly used fatigue analysis method in science and industry today.
Two methods are available to compress data in time domain.
For most test bench investigations its necessary to consider phase and frequency content of multi axial measured loads.
Multi axial load data which are used for FE calculation (FEMFAT MAX) must have correct phase relationship.
To calculate the correlation of customer usage (target) to special test tracks usage (actual) a powerful optimization algorithm is used.
A lot of measurements can be combined to fulfill target damage best within a user defined testing time.
