摘　　要：为了解决复杂结构在动力学响应约束下优化的难题,综合人工以及计算机在复杂结构优化中的优点,提出一种人机交互式优化方法用于载人航天某复杂装置的优化设计。经过结构优化后的装置,在质量保持基本不变的情况下一阶振动频率提升41.1%,正弦试验条件下关心节点的最大加速度响应值减小24.3%,优化效果明显,满足优化设计要求,验证了该优化设计方法的可行、有效。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.
