The new structure optimum design method is presented. It deal with the large-scale structure vibration characteristic problem; divide all structure into the no-change substructure and the design substructure. Make reduction analytical model for the no-change substructure with GDR reduction method; to the design substructure create some basis-vector to adapt to designers needs. Assemble two substructures to the structure, and solve its optimal vibration characteristic result.
