摘要
The present invention discloses a method of evolutionary optimization algorithm for structure design which comprises steps of: meshing a geometric structure with applied geometric boundary conditions; analyzing the meshed geometric structure by finite element analysis to determine the relative stress distribution of the structure; and evolving the geometric structure by migrating geometric boundary nodes. During evolution, meshing and finite element analysis are repeated to perform structural optimization evolutionally till the evolving design converged to an optimum. The present invention overcomes the mesh-dependency problem in most of structural optimization algorithms in the field of structure topology optimization. In addition, the optimized design of the present invention possesses smooth geometric boundaries. Moreover, structure topology resolutions can be controlled and capable of producing designs that are very close to exact theoretical analysis.
