Abstract

This invention discloses a lookup-based deformation matching and electromagnetic mapping digital twin system and method. The system pre-constructs a multiphysics simulation database with velocity as the primary key, storing the deformed 3D model, pressure field data, radar cross section (RCS) data, and feature point displacements, and establishes a deformable-velocity association list for the scaled model. In manual mode, the corresponding multiphysics data is retrieved by directly inputting the velocity; in automatic mode, the displacement detection module detects the displacement of feature points in the scaled solid model in real time and calculates the current deformation. Based on the association list, the velocity primary key is matched in reverse using the minimum absolute difference method, thereby retrieving the corresponding multiphysics data. The deformed 3D model, pressure field pseudo-color distribution, and RCS map are simultaneously displayed on a visualization rendering platform, realizing the digital mapping from solid deformation to multiphysics state.
