Buckling Analysis and Optimization Design of Aerostat Array Structure Based on ANSYS

Aiming at the ground demonstration system of the space solar power station, a large space aerostat array structure is proposed. Finite element software ANSYS is used to establish a three-dimensional model of the truss structure of the array structure and perform the structural buckling analysis in order to determine the stability of the truss structure. With the first-order critical buckling load as the constraint condition, the size and structure of the truss beam section is optimized. The design optimization points are found through response surface analysis and multi-objective genetic optimization algorithm, so that the optimized truss structure realizes the lightweight design under the premise of structural stability, and the load capacity of the system is therefore improved.
