In this research, vibrating screen motion is represented by multi-DOF (degree-of-freedom) dynamic model, which accounts stochastic disturbances from incoming material and impacts on sieving decks. Specific features of vibration signals are analysed to identify springs deterioration modelled as the bilinear stiffness characteristics.
