摘　　要：讨论了标准协同优化方法的流程和特点,并针对固体弹道导弹系统的特点,设计了集成质量、动力、气动、外形和弹道5个学科的弹道导弹多学科设计优化模型。采用协同优化方法集成各学科的知识,协调处理各学科之间的耦合变量,应用合理的优化策略有效地解决了在弹道导弹多学科优化设计中的耦合关系所带来的计算问题,并对该模型成功进行了多学科优化设计,得到了优化方案。研究不但证明了协同优化方法在固体弹道导弹多学科优化设计中的有效性,还表明协同优化方法可使各子学科专注于本学科的优化设计,并使用本学科已有的分析工具,无需考虑对其他学科的影响,这方面相对于其他高要求的MDO方法具有较明显优势。The flow process and characteristics of standard collaborative optimization method were discussed. Aiming at system characteristics of solid ballistic missile, the multidisciplinary design optimization （MDO） model of solid ballistic missile was established, which integrates mass, dynamics, pneumatics, configuration and trajectory. The collaborative optimization （CO）method can integrate multidisciplinary knowledge and coordinate coupling variables among the different disciplines. Some calculation problems of coupling relationship during the multidisciplinary design optimization design were effectively solved by using rational optimum strategy. The model was successfully optimized, and optimization scheme was obtained. The investigation results show that collaborative optimization method is effective for multidisciplinary optimization design, moreover it can make sub-discipline only focus on optimization design of local discipline and use existing analysis tools, without considering the effect on other disciplines, which is superior to other MDO methods.
