Abstract: [Objective] In order to realize the whole-life health monitoring of ships [Method], a hybrid digital twinning system for structural health is designed to collect and feedback the deformation of key cabin structures in real time, and improve the information and safety management capabilities of shipping. The singular value decomposition method is used to compress and reduce the dimension of the physical field information formed by multiple groups of loads to obtain the specific standard orthogonal basis, create the response surface model of the relationship between the basis vector and the load, and output the finite element reduced order model based on the real-time input load. The Kriging interpolation algorithm based on geostatistics is used to arrange points according to the specific topological structure, and the real-time sensor data and the supplementary point data output by the reduced model model are fused and corrected through the Kalman filter algorithm to jointly calculate the deformation of the monitored object. Finally, through the construction of deformation monitoring software and hardware system, the whole process of monitoring physical characteristics collection and visualization is realized. [Results] Under the preset load, the hardware acquisition system can stably collect data, and the supporting application program can visualize the acquisition process in real time according to the expected requirements. [Conclusion] The hybrid digital twinning system of structural health meets the needs of ship health monitoring, and has certain reference significance for the highly integrated and intelligent development of ships in the future.
