The aerodynamic and elastic properties of the airfoil can be improved by the bending-torsional coupling effect of the composite skin structure.In order to maximize the bending-torsional coupling effect of the structure, genetic algorithms are used to optimize the design of such structures and the honeycomb structure is taken as an example for analysis The finite element analysis software is used to analyze the objective function, and the strength of ply and honeycomb sandwich is taken as the constraint function, and the optimization of the finite element method is combined with the genetic algorithm to optimize the structure of the complex problem based on the finite element method Software system
