Other AbstractThe invention relates to a large structure dynamic optimization design method based on structural decomposition. In three-dimensional modeling software, a geometric model of a large member is established, a size variable of an external frame forming a structural member is recognized, and a basic style and the size variable of an internal composition unit are recognized; the external frame of the structural member is subjected to topological optimization, the size of the internal composition unit is optimized, and size data are acquired; the optimized size data are imported into Isight-FD software, optimization iterative analysis is performed on different combinations and different size configurations of the external frame and the internal composition unit according to the constraint condition and the target function, and an optimization result is output. The method is widely applied to lightweight and weight reduction design of a large and heavy-load complicated structure part and has the advantages of capability of realizing design from the simple into the deep as well as fastness and reliability. Due to the robustness of an algorithm, the geometric structure meeting the requirements of mechanical properties can be found only through a few sampling points, and reliable technical support is provided for structure design work of large heavy-load equipment at the present stage.
