Structure deformation fiber monitoring-reconstructing method and system

The invention relates to a structure deformation fiber monitoring-reconstructing method and system. Strain and deformation data is extracted according to a finite element simulation result of a structure, a strain-deformation function relation of multiple lines is fit on the basis of the idea of least squares, and an initial integral deformation field of the structure is obtained by interpolation.A fiber monitoring system is established, strain, temperature and acceleration data of the structure is collected, a strain sequence is reconstructed via an interpolation algorithm according to discrete point data measured by experiments, the strain-deformation function relation is corrected, and further the integral deformation field of the structure is corrected. The system and method are verified in a rectangular plate deformation reconstruction experiment, the deformation state of a tested piece can be obtained effectively via the system and method, the deformation field is reconstructedfor about 2%, and a simula
