Abstract
In order to master the structural response characteristics, a digital twin model of the cruise structural experiment model is constructed to grasp the deformation and interaction mechanism between the main hull and plump superstructure under each loading condition.
The structural matrix of the experiment model is constructed to establish the reduced order model. Furthermore, the real-time response of the cruise structural experiment model can be predicted by the kriging agent model. Subsequently, the experiment model of a cruise ship is taken as the object. Three typical cross-section measuring points are arranged in the midship area to monitor structural response. Ten groups of different working conditions are designed to compare the response characteristics. It is found that the structural response error between the results of the digital twin model and the experiment remains small under each loading condition.
The digital twin model can represent the character of the experiment model effectively. The interaction mechanism between the main hull and superstructure can be investigated using the proposed digital twin model to improve the safety and reliability of the cruise ship structure.
