Reconstruction of Wing Structure Deformation Based on Particle Swarm Optimization Ridge Regression
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 In this paper, a typical airfoil aluminum plate structure is taken as the research object. A structural deformation monitoring and reconstruction method, PSO‐RR (particle swarm optimization‐ridge regression) algorithm, is proposed. A variety of different complex load cases are applied to the airfoil structure, and the strain values at some specific ...
