To solve the problem of the structural optimization of a complicated structure under dynamic response constraints, a human-computer interaction method is proposed to take the advantages of human and computer in the structural optimization, and it is used in the structural optimization of an aerospace assembly. The assembly, after the structural optimization, exhibits remarkable performance improvement in that the first integral vibration frequency increases 41.1% and the maximal the frequency response acceleration of cared points drops 24.3% under the sinusoidal vibration test load conditions while the mass remains essentially unchanged. The result satisfies the requirement of the optimal design and proves the effectiveness and feasibility of the method.
