Abstract

The comparisons of the displacement and strain modal parameters were researched for the vibrating screen upper beam with fatigue damaged crack. The results show that the modal frequencies and the displacement mode shapes have little difference between intact and damaged upper beam, but the strain mode shapes have obviously mutation for the fatigue damaged upper beam. Therefore a damaged indicator is defined as the rate of strain modal change between damaged and intact beam. The rate of strain modal change increases with the increasing damaged degree of the vibrating screen upper beam. The prediction of the damaged degree of the upper beam can provide reference for maintenance forecast of the vibrating screen upper beam, which can ensure safe and reliable operation of the vibrating screen.
