A Method for Morphological Reconstruction of Long Board Structure based on Segmented Calibration of Resistance Strain Gauges

Researches on the morphological sensing and reconstruction methods for key long board structure of aerospace vehicles are of great significance to the safe and reliable operation of these spacecraft. Therefore, a method for morphological reconstruction of flexible long board structure based on the segmentation calibration of resistance strain gauges is proposed in this paper. The morphological reconstruction algorithm of long board structure based on strain information is introduced at first. Then, a long board model morphology visualization experiment platform is constructed, and an optimized arrangement and segmented calibration method for the resistance strain gauges array is explained. Finally, the verification of real-time sensing and reconstruction experiments of the long board structure is performed. The results show that the morphological perception and reconstruction effect of long board structure experimental model is expected, which verifies the feasibility and effectiveness of the proposed method.
