Complex shell structure analysis and optimization based on isogeometric analysis and simulated annealing algorithm
This paper proposed a shell structure analysis and optimization algorithm based on the isogeometric method and simulated annealing,aiming to enhance the efficiency of CAD and CAE integrated design for complex shell structures.Firstly,based on NURBS technology,the parametric modeling of the thin shell structure was carried out,and then the isogeometric analysis was realized based on the Kirchhoff-Love shell theory.Then,based on the simulated annealing algorithm,the geometric parameters of the shell served as the design variables,while multiple mechanical properties acted as the objective functions for optimization,thus realizing the integration of isogeometric analysis and intelligent optimization algorithm for shell structure analysis and optimization.Finally,the effectiveness of the algorithm was verified through two examples.Compared with traditional finite element methods,this algorithm has the advantages in precision and efficiency.
