Abstract

fetched live from OpenAlex

Large flexible structures are used in many space applications, for example, satellite communication antennae, space robotic systems, and space station, etc. The flexibility of these large space structures results in problems of structure shape deformation and vibration, etc. In recent years, active shape control is developed to improve the performance of these flexible space structures. However, it is difficult to measure the surface shape of large flexible space structures in space environment. In this paper, a shape estimation method was developed to determine deflection of annular structures under arbitrary loading and boundary conditions. The shape estimation method utilizes strain information from strain gage sensors mounted on the structure. The strain field is calculated using polar components of stress in terms of Airy’s stress function. The coefficients of each function are determined based on the relationship of strain, displacement, and strain compatibility. The strain field is constructed by least squares smoothing procedure. This shape estimation method was verified by the numerical method, finite element and the experimental results. The results show that the shape estimation method can be used to determine deformation shape of the annular plate for active shape control of flexible structures.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
