【Abstract】 Spacecraft design is a complicated mixed-variable problem, and designer’s experience takes a very important role in solving such a problem. Considering the characteristics of spacecraft design, a man-machine interactive optimization method was used in structural design of a satellite, where the cross-sectional variables were optimized by numerical algorithm, and the topology variables were adjusted with man-machine interactive ways. Structural analyses for various kinds of response were correspondingly devided into two parts; basic structural analysis and comprehensive structural analysis, being carried out in cross-sectinal optmization and topology adjustment respectively. After iterations the final satisfactory design that met all the required constraints was tormed. The application result shows that the method works satisfactorily and effectively.更多还原
