Abstract: To ensure the integrity of the digital twins in the virtual-reality symbiosis stage, the problem that the finite element deformation and failure models can only be displayed in the software and cannot be exported needs to be solved. In this paper, a finite element reconstruction technique is developed through the biomimetic study of natural objects. First, the deformation data in the finite element is obtained by the 'hexagonal method' and 'slice method' through the study of mathematical principles and development based on Visual Studio, then the model format that can be recognised by the 3D printing equipment is reconstructed, smoothed, and optimised, and finally the modified model in the finite element is presented by using prototyping 3D printing technology rapidly. The innovation of the method and the development of the reconstruction algorithm solved the problem that digital twins can not accurately perceive the transient deformation of virtual realilty, which has strong application value and practical significance.

Keywords: digital twins; finite element analysis; model reconstruction; full-life cycle; virtual-reality symbiosis.
