AI Technical Summary

Technical Problem

Existing technologies cannot effectively identify early latent fatigue damage under varying operating conditions of lifting machinery, resulting in missed detection of latent defects and delayed inspection results. This is mainly because multimodal deep learning models do not incorporate fracture mechanics damage evolution mechanisms and cannot distinguish between real fatigue damage and pseudo-features caused by operating condition disturbances.

Method used

By employing a multimodal large model combined with a numerical simulation program for fracture mechanics fatigue damage evolution, and through edge preprocessing and spatiotemporal decoupling and causal reasoning in the cloud, a closed-loop coupled architecture driven by both data and mechanism is constructed. False features are eliminated and damage-sensitive feature vectors are extracted. Feature extraction weight parameters are optimized to generate early latent damage features.

Benefits of technology

It effectively identifies early latent fatigue damage in lifting machinery, reduces the delay in inspection results, improves the detection accuracy of latent defects, reduces interference from false features, and realizes real-time monitoring and early warning of structural status.
