Research on the Modeling Method of Mould Bed Twin for Ship Segment Construction

As an important tool for deformation control of ship subsection construction, the mould bed is the key to responding to subsection construction quality quickly. Therefore, this paper constructs a digital twin for ship segment construction by studying the operation state of the mould bed. Firstly, the relationship between the physical model and the virtual model is modeled for the physical entity of the ship's mould bed. Secondly, the industrial Internet of Things is used to transmit the data of each unit to the virtual model in real-time, through which the virtual model can be fed back and adjusted. Finally, based on Unity 3D platform, a digital twin system of Marine mould bed is developed for ship segment construction, and the support height of the ship mould bed is taken as a case to verify the correctness and effectiveness of the model and method constructed in this paper.
