FATIGUE DAMAGE ANALYSIS OF VIBRATING SCREEN UPPER BEAM BASED ON STRAIN MODAL ANALYSIS

The displacement and strain modal parameters identification models of the vibrating screen were built based on modal theory,the variations of the displacement and strain modal parameters were analyzed for the vibrating screen upper beam with fatigue damage crack. The results show that the modal freq...
