Curve fiber variable stiffness composite material structure integrated optimization method

The invention discloses a curve fiber variable stiffness composite material structure integrated optimization method, and belongs to the field of composite material structure optimization. The implementation method comprises the following steps: defining and creating an initial'base layer 'of the curve fiber variable stiffness composite material structure, constructing a number field representing the existence of each single layer of the'base layer', and establishing an integrated optimization problem model of the curve fiber variable stiffness composite material structure, which integrates the number of layers, the thickness of the layers and the laying angle of the curve fiber; based on a Latin hypersquare sampling test, constructing a mixed correction mode variable fidelity proxy model in an exponential form; performing discrete continuous mixed variable optimization by adopting a genetic algorithm to obtain a preliminary optimization result; reconstructing an optimization problem only containing fiber pat
