针对带子星航天器总体参数多学科设计优化(MDO)问题,进行系统任务分析和学科耦合关系分析。考虑有效载荷、轨道和结构等学科设计变量和约束条件,以航天器有效接近区和整星质量的综合指标为目标,建立MDO模型和相应分析模型。利用iSIGHT软件搭建求解平台,采用基于罚函数的协同优化(CO)算法对所建立的MDO模型进行仿真计算,并得到合理结果,验证了所建立的MDO模型的合理性和CO方法求解航天器MDO问题的有效性。对MDO问题的建模和求解过程为航天器MDO问题研究提供了一种典型示例,所建立的各学科分析模型可为同类问题提供参考。
Aiming at the multidisciplinary design optimization (MDO) problem of the overall parameters of the band-spacecraft, the system task analysis and discipline coupling relation analysis are carried out. Considering the design variables and constraints of the payloads, orbits and structures, the MDO model and the corresponding analysis model are established with the comprehensive indicators of the effective spacecraft approaching zone and the overall mass. Using iSIGHT software to build a solution platform, the penalty function-based collaborative optimization (CO) algorithm was used to simulate the established MDO model and the reasonable results were obtained. The rationality of the established MDO model and the CO method to solve the spacecraft MDO The validity of the problem. The process of modeling and solving MDO provides a typical example for the research of spacecraft MDO. The established disciplinary analysis models can provide reference for similar problems.
