Abstract EN
In view of the problems of lagging and poor predictability for ship assembly and welding quality control, the digital twin technology is applied to realize the quality prediction and control of ship group product.
Based on the analysis of internal and external quality factors, a digital twin-based quality prediction and control process was proposed.
Furthermore, the digital twin model of quality prediction and control was established, including physical assembly and welding entity, virtual assembly and welding model, the quality prediction and control system, and twin data.
Next, the real-time data collection based on the Internet of Things and the twin data organization based on XML were used to create a virtual-real mapping mechanism.
Then, the machine learning technology is applied to predict the process quality of ship group products.
Finally, a small group is taken as an example to verify the proposed method.
The results show that the established prediction model can accurately evaluate the welding angular deformation of group products and also provide a new idea for the quality control of shipbuilding.
