Abstract: The present invention relates to a targeted perception-oriented twin substructure interaction method and system, and application. The method includes: acquiring multivariate inspection and monitoring data and finite element influence line data of a main structure; solving, on the basis of the inspection and monitoring data and the finite element influence line data of a non-focus region, boundary conditions of a focus region; establishing, for the focus region, a refined twin substructure finite element model, and correcting material properties of the refined twin substructure finite element model on the basis of the inspection and monitoring data and the finite element influence line data of the focus region; and calculating a correction force on the basis of the boundary conditions of the focus region and the material properties, and using the correction force as an equivalent external load to act on nodes of a global finite element model.
