AI Technical Summary
Existing methods for predicting the fatigue life of grouting connection structures for offshore wind turbines are limited by data acquisition constraints, making it difficult to accurately predict their fatigue life and threatening the operational safety of offshore wind turbines.
A method combining convolutional neural networks (CNN) and long short-term memory networks (LSTM) is adopted to extract spatial feature information from CT scan images of grouting connection structures. The fatigue life prediction model is trained by combining the loss function of physical constraints, so as to achieve accurate prediction of the damage state and fatigue life of grouting connection structures.
With limited data, it is possible to accurately predict the fatigue life of grouting connection structures, reduce reliance on large-scale fatigue testing, and ensure the safe operation of offshore wind turbines throughout their entire life cycle.
