一种基于信息熵的机身筒段调姿弯曲变形的监测方法
By using an information entropy-based monitoring method, the three-dimensional coordinates of the aircraft fuselage section are measured using a laser tracker. The bending deformation index and pass rate are calculated, and information entropy and weights are established. This solves the problems of neglecting the relationship between indicators and low data processing efficiency in traditional methods, and achieves a more comprehensive attitude adjustment quality evaluation and process optimization.

AI Technical Summary
Traditional methods for evaluating the attitude adjustment quality of aircraft fuselage sections focus only on deviations of individual indicators, neglecting the relationships between indicators. This results in low data processing efficiency, difficulty in identifying the causes of deviations under the combined effect of multiple factors, and leads to the neglect of potential problems and difficulty in identifying process issues.
An information entropy-based monitoring method is adopted. The three-dimensional coordinates of the aircraft's horizontal measurement points are measured by a laser tracker. The bending deformation index and pass rate are calculated, information entropy and weights are established, and statistical methods are used to identify attitude adjustment quality problems and optimize the process.
It provides a comprehensive evaluation method to identify systematic deviations, improve data processing efficiency and accuracy, help locate key process steps, and provide a basis for production optimization.
