On-line damage identification of vibrating screen beam based on strain energy

To identify quickly,accurately on-line damage location,an on-line damage identification method is proposed based on the strain energy normalization algorithm,and then its feasibility is validated by experiment. The experimental results show that this method can quickly,accurately identify the damage location of vibrating screen beam to accomplish on-line damage identification; which can be significant for the real-time monitoring fault of vibrating screen beam.
