Abstract EN
A novel damage identification method based on transmissibility function and support vector machine is proposed and outlined in this paper.
Basically, the transmissibility function is calculated with the acceleration responses from damaged structure.
Then two damage features, namely, wavelet packet energy vector and the low order principal components, are constructed by analyzing the amplitude of the transmissibility function with wavelet packet decomposition and principal component analysis separately.
Finally, the classification algorithm and regression algorithm of support vector machine are employed to identify the damage location and damage severity respectively.
The numerical simulation and shaking table model test of an offshore platform under white noise excitation are conducted to verify the proposed damage identification method.
The results show that the proposed method does not need the information of excitation and the data from undamaged structure, needs only small size samples, and has certain antinoise ability.
The detection accuracy of the proposed method with damage feature constructed by principal component analysis is superior to that constructed by wavelet packet decomposition.
