Abstract

In order to solve the problem of damage identification of oil derrick steel structure under noise background, a damage identification method based on energy entropy difference is proposed. First, the signal is denoised by stochastic resonance, then the denoised signal is decomposed according to Hilbert Vibration Decomposition (HVD), and the amplitude spectrum energy entropy difference is calculated and used as the damage index; taking the ZJ70 oil derrick steel structure laboratory model as an example to carry out experimental analysis. The results show that this method can identify the damage location of oil derrick steel structure effectively and accurately.
