The simulation model referred to the paper is wing structure based on high-aspect-ratio near-space aircraft, the multipoint discrete curvature information of wing structure can be detected based on space-division multiplex technique and wavelength division multiplex technique of FBG sense network; In order to apperceive the vibration shape of wing accurately, the interpolation arithmetic of curvature is analyzed; The space-curved-face 3D-reconstruction method and algorithm process are analyzed and researched with the coalesce of moving coordinate system, curvature vector and osculating plane; Combining computer's graphics processing technology to develop simulation testing environment, 3D-reconstruction and visualization of vibration shape of simulation wing structure based on high-aspect-ratio near-space aircraft are realized. Simulation results show that the adopted 3D-reconstruction method based on discrete curvature for wing structure and visualization technology can reflect low modal real-time vibration shape of the space-curved-face structure of simulation wing more accurately.
