Abstract EN
The working environment of seawater axial piston hydraulic pump is harsh, and it is difficult to diagnose due to insufficient fault database.
In contrast, pumps of the same type but using hydraulic oil have an adequate fault database and are easy to diagnose.
In view of the above situation, a fault diagnosis method of seawater hydraulic piston pump based on transfer learning is proposed.
The method decomposes the original sampled fault signal by complementary ensemble empirical mode decomposition (CEEMD) to obtain the intrinsic mode function (IMF) that can characterize the original signal.
The singular value decomposition (SVD) is performed on the IMF.
Then, the obtained singular value is used as a feature parameter to construct a feature vector.
The feature data of seawater hydraulic pump and oil pump are used as target data and auxiliary data to form training data.
The training data is trained based on the iterative adjustment of the weight through the TrAdaBoost transfer learning algorithm.
Finally, the results of diagnosis and classification are compared with traditional machine learning.
When the number of training data is 5 groups, the accuracy of transfer learning is 30.5% higher than that of traditional machine learning.
The results show that transfer learning has great advantages in the case of a small number of samples.
