Material structure integration topological optimization method based on ordered MFSE interpolation

The invention provides a material structure integration topological optimization method based on ordered MFSE interpolation, and belongs to the field of high-performance carrying equipment material structure integration design. The optimization method mainly comprises four parts, namely generation of a regular hexahedral mesh with any structure, a macroscopic ordered material field series expansion multi-material interpolation method, a microscopic correlation function driving connectivity method and structure multi-scale concurrent topological optimization. According to the method, extra constraints are not introduced in the optimization process, connectivity between microstructures can be achieved, meanwhile, the number of design variables is greatly reduced, and the efficiency of topological optimization is greatly improved; the method is expected to be applied to integrated topological optimization design of material structures of small aerospace parts and can be popularized to the high-complexity problem
