Summary:In the cement industry components are designed by using the finite element method. This practice is verified by strain measurements on machines in industrial use, utilising rainflow counting. A calculation model was developed for the assessment of such data. The model was calibrated for EN-GJS-400-15U by constant and random amplitude fatigue tests, based on measurement data. For test preparation, a method of omitting load cycles prior to load sequence reconstruction was developed. The experimental results show a satisfactory accuracy when using a constant characteristic damage sum, which can be improved by considering the damage potential of the load spectra.
